SERMON: SANCTIFICATION
Text:
1 Thessalonians 4:3 – “For this is the will of God, even your sanctification, that ye should abstain from fornication.”
Introduction
Sanctification is one of the most important works of God in the life of a believer. Many Christians talk about salvation, but few understand sanctification.
Salvation saves you from sin.
Sanctification separates you from sin.
When God saves a man, He does not leave him the same way. God begins a process of purifying, cleansing, and transforming that life.
Hebrews 12:14 says:
“Follow peace with all men, and holiness, without which no man shall see the Lord.”
This shows us that sanctification is not optional for a Christian.
1. What is Sanctification?
Sanctification means to be set apart for God and made holy.
It is the process where God cleans a believer from sin and shapes him into the image of Christ.
Example in the Bible:
Before a vessel was used in the temple, it had to be sanctified.
2 Timothy 2:21
“If a man therefore purge himself from these, he shall be a vessel unto honour, sanctified, and meet for the master's use.”
This means God cannot use a dirty vessel.
God wants clean vessels.
2. Sanctification is the Will of God
Many people ask:
“What is God's will for my life?”
The Bible already answered it.
1 Thessalonians 4:3
“For this is the will of God, even your sanctification.”
God's will is not first cars, marriage, or money.
God's will is your holiness.
Before God gives you great things, He wants to make you a holy person.
3. Sanctification is a Process
Sanctification does not happen in one day.
It is a daily walk with God.
2 Corinthians 3:18
“But we all... are changed into the same image from glory to glory.”
That means:
Today you are better than yesterday.
Tomorrow you become more like Christ.
God is gradually transforming your life.
4. Things Sanctification Removes
When sanctification begins, certain things must leave your life.
1. Sexual immorality
1 Thessalonians 4:3
2. Worldliness
1 John 2:15
3. Sinful habits
Romans 6:22
A sanctified life begins to hate sin and love righteousness.
5. How Sanctification Happens
1. Through the Word of God
John 17:17
“Sanctify them through thy truth: thy word is truth.”
The Word cleans your mind and heart.
2. Through the Holy Spirit
2 Thessalonians 2:13
The Holy Spirit convicts you when you do wrong and leads you to holiness.
3. Through obedience
Sanctification grows when you obey God daily.
6. Signs of a Sanctified Life
A sanctified believer will show these fruits:
• Hunger for God's word
• Hatred for sin
• Love for righteousness
• Desire for prayer
• A transformed lifestyle
Galatians 5:22-23 shows the fruits of the Spirit.
Conclusion
Sanctification is God's work to make you holy and prepare you for heaven.
Without sanctification:
You cannot please God.
You cannot represent Christ.
You cannot see the Lord.
That is why Hebrews 12:14 says:
“Without holiness no man shall see the Lord.”
