John 3: 16
In the beginning God provided the means for forgiveness in the form of a blood sacrifice. This sacrifice would allow all of mankind the opportunity to have their sins forgiven and bring them back into a right relationship with God. This is also the time period that other sacrifices, and offerings were started. We also find that God often spoke directly with people. God would also be teaching people how to live and teaching them what his will was.
The time came that God wanted to give the people written instruction of how to live. The ten commandment told us what our relationship was to be with God and other people. The rest of the law that was given, gave us instruction of how to worship God and how we are to treat others. God knew we could never live without sin in our lives so he continued the sacrifices.
When the time had fully come God sent us his son. He was the son of man and the son of God. He taught the word of God and he proved he was God by the miracles and signs that he did. His next teaching was that no one could enter heaven unless they believed on him and were filled with the spirit of God – see Acts 2. His final act was to become the sacrifice for sin by dieing on the cross. He was fulfilling the law in order to place the law in our hearts.
Since we know that God sent Jesus into the world to redeem us, what is our response to him. Our verse today tell us that we are to believe in him. Believing can come in two types. The first is that we believe and then live our lives the way we want to. A story is told that a person was about to enter heaven and was asked why he should be let in. the person said that he attended church, paid his tithe, shared his faith with others and was an all round good person. Jesus looked at him and said that he did not know him and would not be able to inter heaven. The other type of belief that we need to have is like when a person was asked why he should be let into heaven he said that he had been a sinner but he now let Jesus guide his life. He had a personal relationship with Christ. He learned the scriptures, prayed, met with fellow believers at a regular time, and allowed the spirit of God to direct his life.
We imitate Christ because we believe that he will guide our lives and we will be able to enter heaven
