Sermon Summary: Genesis 18:1-15 & romans 5:1-11 “Promises”
Humanity does not have a good track record of keeping promises to God, other people, and even ourselves. Just think of how many New Year’s resolutions are quickly broken. The problem is sometimes we have no intention of keeping a promise; while other times we make it sincerely, but soon forget about it. People also can come to a point that keeping a promise becomes inconvenient, or we simple do not wish to keep it. Then there are promises we make and want to keep but simply cannot because they are beyond our power or skill to do so.
In contrast to human beings, the Lord our God has an excellent track record when it comes to keeping promises. First, God never makes a promise he does not intend to keep. Secondly, God does not get distracted or bored, or forgetful about anything including promises; even though sometimes we think that might be the case.
Finally, there is nothing the Lord promises that is beyond his control to fulfill. When it comes to God, however, his promises do not often have a specific time frame. His timing is not like ours and so it may seem that the Lord has forgotten or has changed his mind, or can’t do what he promised. But when God does say a promise will be fulfilled within a certain time frame it does happen.
Today’s reading from Genesis concerns both kinds of time frames when it comes to God’s promises.
God made a promise to Abraham that through his wife Sarah he would have a son. But then a little over two decades went by, and nothing happened.
Finally, the time came when both of them no longer really expected God to keep his promise, since Sarah became much too old to have a baby. In Genesis chapter seventeen, the Lord reaffirms his promise to Abraham. Listen to his response: “Then Abraham fell on his face and laughed and said to himself, “shall a child be born to a man who is a hundred years old? Shall Sarah, who is ninety years old, bear a child?”
But God insisted a child would come through Sarah-since his son Ishmael was not the promised child.
Sometime after this Abraham was outside his tent when he saw three men traveling his way. He immediately offered them hospitality, which was the cultural norm of that time and place. They accepted, and Abraham himself saw to their needs.
These men, were possibly angels, but many believe at least one was God appearing in the form of a man. Either way, when one of them spoke to Abraham to say Sarah would have a son within a year, he was speaking with the voice of God.
Sarah, who was in the tent overheard this promise and laughed to herself because it seemed impossible.
The Lord heard her silent laugh and called her out, which was when she, probably out of fear, lied to God. But the Lord knew the truth and she was challenged to have faith when he said: “Is anything impossible for God?”
The question, of course, was rhetorical, since God has the power to do anything that God wishes to do.
Jesus, as recorded in Mark 10:27, would later affirm the truth of God’s power. When speaking about salvation he tells his disciples: “For mortals it is impossible, but not for God; for God all things are possible.”
And for Abraham and Sarah God did the impossible- a year later she gave birth to a son. God commanded the baby to be named “Isaac”, which means “laughter”, revealing God also has a sense of humor. So, we can see that today’s reading from Genesis contains a call to trust in God’s ability to do whatever it is he wishes- for, through, and in us.
It is, of course, easier for us say we trust in God no matter what, than to live out this belief. This is why again and again the Bible reminds us to trust in the Lord.
The reading from Paul’s letter to the church in Rome is a good example of this. He was writing to Christians who thought they had reason to doubt their salvation because they were not Jewish.
There were some Jewish Christians who insisted, to really be sure of salvation, a person had to follow all the Old Testament laws and traditions.
Paul insisted this is not the case because Jesus’ sacrifice provided salvation for Jew and non-Jew on an equal basis, through God’s grace and our faith. In the sentences preceding today’s reading, the apostle explains Jesus was handed over to death for our trespasses and raised for our justification. Paul rejoices in God’s grace and love revealed in Christ’s death and resurrection, which makes peace between us and our creator, whom we all rebelled against.
It is because we are now justified- meaning reconciled with God through Jesus, we have hope and new life even though we are still sinners. This is a sure and certain hope because it is based on God’s promises and Christ’s sacrifice; and not on our words or actions. The apostle in particular is reminding his readers that one of the benefits of being justified through faith in Christ is- the Spirit’s presence that can empower us to endure and grow when our own resources fail.
His confidence that our hope in the Lord triumphs over all adversity in life is drawn from the fact Jesus died for sinners -meaning all kinds of people. Paul is therefore able to face suffering, especially for the faith, not because he is certain things will eventually get better, but because of his hope that God will have the final word.
Paul, however, does not say we should want to suffer or it is wonderful when we do suffer, as some people mistakenly think. Instead, he insists Christian suffering is not a sign God has broken his promise to Us. To the contrary, God’s faithfulness remains with us even when we suffer, and for that we can continue to rejoice that we are loved and saved.
He assures Christians that God can and will bring some positive things out of suffering even when it seems impossible to us. He gives the example of how with the help of the Holy Spirit, we can endure, if not overcome, what mortal life can throw at us. This endurance also builds character, which is what the apostle himself experienced.
And the love and grace of God demonstrated in Jesus includes our ability to continue on the right path in our Christian journey, against all odds. This perseverance on our part works with God to bring out of adversity hope for new life.
A powerful example of hope and new life coming out of a terrible incident is found today in NYC on the site where the twin towers once stood. The towers, along with other buildings and things around them were destroyed. and almost 3,000 lives that day, and in the aftermath, were lost.
There were also some trees planted near the towers. several months after the attack a worker on clean up duty saw a branch poking out of the debris field, and it had given off some leaves. When it was dug up. although it was partially burnt it was still alive because its roots were healthy. The New York City parks and recreation department took custody of the tree, and brought it to a nursery in the Bronx.
They worked hard to save it. by the following spring, the tree had recovered and bloomed with life. It is now planted on the 9/11 memorial site. And every year, seedlings cultivated from the “Survivor Tree” are gifted to communities around the world. They go to places that have endured tragedy and hardship, helping to spread its legacy of hope. This tree is an example of how God can bring life out of death and a sign of hope from tragedy. If God can do that with a tree we can trust in God’s promise through Christ to do even greater things through people.
Paul’s message to the church of Rome is the same message through scripture given to Christians today. We can trust in God’s promises and rejoice in his love and faithfulness in the midst of suffering, grief, and uncertainty.
This compliments Jesus’ call for us to lean on him, found in Matthew 11:29, where he said: “Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls.”
This is the heart of biblical hope, which is anchored in God’s trustworthiness and power, his love and grace, and not in human emotions or views. This hope also shows us that just like our spiritual ancestors we may laugh and cry, doubt and fear, and wonder about God-but the Lord loves us always God is faithful when we are not, and more patient than we are able to be.
May we learn from Paul’s words to the church in Rome and his encouragement for them to hold on to faith as much as they are able to. And if the time comes when we feel we are not able, let us turn to- rather than away from- the Lord. May we lean on Jesus and let him help us. Amen
