REASON XVII
BECAUSE IT TEACHES THAT A CHANGE OF HEART IS
INDISPENSABLE TO MAN'S SALVATION
I. INTRODUCTION
A RELIGION which does not touch and change the heart is not the religion given by the Christ. The heart is the spring from which our actions flow. If the heart has been defiled by sin, a black and wicked conduct flows therefrom. ''For out of the heart come forth evil thoughts, murders, adulteries, fornications, thefts, false witness, railings'' (Matthew 15:19). These heinous sins are first committed in the heart. If the fountain is kept pure, the stream will be pure. If man's heart is kept pure, his life will be pure. This should be sufficient to prove the absolute necessity of a change of heart. However, the charge has been made that the members of the church of Christ do not believe in a change of heart. The reader immediately recognizes the accusation to be false and unjust. The charge has doubtless grown out of man's ignorance of what the heart is, the analysis and exercises of it, and how it is changed, rather than out of maliciousness. This subject is one of the most discussed and least understood of all sermon topics. But God cannot be blamed for this confusion, for the Scriptures present the subject in a plain and comprehensible manner.
II. THE TWOFOLD NATURE OF MAN
The term heart is defined as the seat of life. The outward and visible man's heart is the hollow muscular organ in the left side, which keeps up the circulation of blood. Many have spoken of this lobe of flesh as though it were the subject of the gospel. How many times we have seen men pound themselves on the left chest and hear them exclaim, ''I feel it right here!'' They speak of the change of heart as though it were the heart of flesh in the chest cavity. Their misunderstanding has arisen in their failure to observe that the Bible teaches that man is both an outward and inward being, physical and spiritual, and that each has a seat of life or heart. Paul, in speaking of the dual nature of man, says, "But though our outward man is decaying, yet our inward man is renewed day by day" (2 Corinthians 4:16). When the heart of the outward or physical man is pricked, death follows. We have an example of this in 2 Samuel 18:14; ''He took three darts in his hand, and thrust them through the heart of Absalom. '' But when the heart of the inward or spiritual man is pricked, the outward man is untouched. For instance: "Now when they beard this, they were pricked in their heart, and said unto Peter and the rest of the apostles, Brethren, what shall we do?'' (Acts 2:37) The hearts of these Jews were pricked with the gospel and they lived. Absalom 's heart was pricked with darts and he died. The two different hearts were acted upon by two different weapons. It was the heart of the inward man that the gospel touched. It is evident that this is the heart which is changed in conversion to God. This fact is made still plainer by studying the analysis of the heart and its exercises.
III. THE ANALYSIS AND EXERCISES OF THE HEART
1. The heart is that part of man called intellect, which:
(1.) Thinks. ''Wherefore think ye evil in your hearts?'' {Matthew 9:4)
(2.) Reasons. "Why reason ye these things in your hearts?'' (Mark 2:8)
(3.) Understands. "Understand with their heart." (Matthew 13:15)
(4.) Believes. "With the heart man believeth." (Romans 10:10)
The Bible says that the human heart thinks, reasons, understands and believes. God. calls this part of man the heart, but man calls it the intellect. So what the Bible ascribes to the heart, man attributes to the intellect.
2. The heart is also seen to be that attribute of man called emotion, which:
(1.) Despises. "She despised him in her heart." (2 Samuel 6:16).
(2.) Desires. "Brethren, my heart's desire and my supplication to God is for them, that they may be saved.'' (Romans 10:1).
(3.) Loves. "Thou shalt love the Lord thy God with all thy heart." (Matthew 22:37).
(4.) Trusts. "Trust in Jehovah with all thine heart." (Proverbs 3:5)
So what God calls the heart, man calls the emotions. We see that man's heart embraces man's feelings, sensibilities or emotions. God's word says the heart despises, desires, loves and trusts.
3. The heart is that quality of man called will, which:
(1.) Determines. "Hath determined this in his own heart." (1 Corinthians 7:37)
(2.) Intends. "The thoughts and intents of the heart." (Hebrews 4:12)
(3.) Purposes. ''That with purpose of heart they would cleave unto the Lord." (Acts 11:23)
(4.) Obeys. "Ye became obedient from the heart." (Romans 6:17)
So the heart determines, intends, purposes and obeys. Man calls this quality the will or volition. God calls it the heart.
4. The heart is that faculty of man called conscience, which:
(1.) Condemns or condemns not. ''If our heart condemn us, God is greater than our heart, and knoweth all things. Beloved, if our heart condemn us not, we have boldness toward God." (1 John 3:20, 21)
The Bible speaks of a part of man which condemns or approves. God calls this part the heart. Man speaks of it as the conscience. The above scriptures make it plain that the heart of the inward man is that part of man which embraces the intellect, emotions, will and conscience. It includes the whole of man's inner nature.
IV. CHANGE OF HEART
1. A complete change is needed. If the human heart embraces the intellect, emotions, will and conscience, there can be no. complete change of heart until each has been changed. Each must be changed, if man's whole heart is changed. The heart must be changed from evil thoughts to good thoughts, from wicked reasoning to good reasoning, from ignorance of God's word to a knowledge of it, from unbelief to belief, from despicableness to admiration, from the detestation of good to its desire, from the love of the world to the love of the Lord, from trust in material things to trust in God, from unrighteous determinations to righteous determinations, from unscriptural intentions to scriptural intentions, from unholy purposes to holy purposes, from disobedience to obedience, and from a condemning conscience to an approving conscience. This is the change of heart which is essential to man's salvation.
2. How is the human heart changed?
(1.) The intellect is changed by evidence or testimony. It is changed from one state to another according to the evidence presented. Thomas' thoughts, reasoning, under standing and faith were not changed until Jesus appeared and said to him, ''Reach hither thy finger, and see my hands; and reach hither thy hand, and put it into my side : and be not faithless but believing.'' Thomas then exclaimed, "My Lord and my God." (John 20:24-29). Consider another example: Not so long ago the father and mother of a sailor received a telegram from Washington stating that their son was killed in the Pearl Harbor attack. Their thoughts, reasoning, understanding and faith were wholly changed. A few weeks later they received another telegram from the same authority saying that the first was all a mistake and that the boy was alive. This testimony produced another change in intellect. Thus it is easy to see that evidence or testimony controls the intellect. The word of God is the testimony God has given to change man's intellect: ''These are written that ye may believe.'' {John 20:31). Again, "So belief cometh of hearing, and hearing by the word of Christ." (Romans 10 :17).
(2.) The emotions are changed by faith in the testimony presented. It is the testimony believed that produces the change in emotions. Despicableness, desire, love and trust are the effects of the thing believed. The mother and father spoken of in the above paragraph had gladness turned to sadness and vice versa because of the thing believed. It is faith in the testimony of Christ that produces the change in the sinner's emotions from the desire of evil to the desire of good, from the love of the world to the love of Christ, and from trust in material things to trust in the Lord.
(3.) The will is changed by motives produced by faith. Saul determined, intended and purposed not to obey Christ, thinking that He was an imposter. We see this persecutor with a determined will traveling on the road to Damascus to persecute Christians. Saul had no New Testament to read, but the audible word of Christ changed his heart from unbelief to belief. When he was told to be baptized and wash away his sins (Acts 22:16), he unhesitatingly obeyed. A disobedient heart was changed by motives produced by faith: belief in the goodness of Christ (Romans 2:4), a motive; belief in the reward of the obedient (Hebrews 5:9), a motive; belief in the punishment of the disobedient (Revelation 20:15), a motive. Saul's sins were washed away in the act of obedience. An obedient heart is indispensable to man's salvation. One becomes free from sin and a servant of righteousness by obeying from the heart: ''Whereas ye were servants of sin, ye became obedient from the heart to that form of teaching whereunto ye were delivered; and being made free from sin, ye became the servants of righteousness" (Romans 6:17, 18). The degree of faith which leads to salvation is a belief with all the heart which incites complete obedience from the heart. No man is a servant of Christ until he obeys from the heart. No heart is right until it is an obedient heart.
(4.) The conscience is changed by faith in having done right. If a man understands and believes what Christ has commanded, he can never have an approving conscience until he does it. For instance, baptism is a command (Acts 10:48); this being true, if one understands and believes baptism is a command to be obeyed in order to enjoy the remission of sins (Acts 2:38), he cannot have a clear conscience until he has been baptized : ''Which also after a true likeness doth now save you, even baptism, not the putting away of the filth of the flesh, but the interrogation of a good conscience toward God, through the resurrection of Jesus Christ (1 Peter 3:21). It is faith in having done right, having obeyed the commands of God, that changes the condemning conscience. The conscience does not hurt until one believes he has done wrong. This is why multitudes are in disobedience to God with an approving conscience. They just do not know or believe they are living in disobedience. This was true of Saul. He, with a conscience as clear as crystal (Acts 23:1), persecuted Christians, and did not have a condemning conscience until he learned and believed the truth. Saul's condemning conscience was then changed to a state of approval by obeying Christ. When man's intellect, emotions, will and conscience are changed, man's whole heart is changed. It is evident that some who have talked the most about "heartfelt religion," a changed heart, have really said the least. They preach only a partial change of heart, telling the people that belief only, a changed intellect, is the only essential item in man's salvation. But conversion to God demands a change of the whole heart. Such includes a change of intellect, emotions, will and conscience. Is it not, then, easy to see which religious organization preaches the religion of the whole heart?
