What’s Jesus main purpose in your opinion then?
Gods sent him. What did he accomplish?
He came so that we could have life, and have it abundantly. He came to seek out and save sinners. He came to spread the Good News. He came to serve us and give his life for us. He came to break down dividing walls. He came to set the oppressed free. He came to heal the sick. He came to find the lost. He came to bind up the brokenhearted. He came to be the light, so we would not be lost in darkness. He came to bring eternal life. He came to bear witness to the truth. He came to reconcile us to God. He came to reconcile us to each other. He came to destroy the power of death. He came to bring us the grace of God. He came to show us God's glory. He came to allow us to partake of the divine nature. He came to suffer and be tempted, so he could help us when we are tempted. He came to show us how to live. He came to teach us how to love.
All of those are pretty much direct quotes from the New Testament. But if you want me to summarize a little and put it into my own words instead of Biblical language, I'd say:
1. He came to teach us how to live
2. He came to show the despised, the sinners, the lost, the sick, the oppressed, the brokenhearted, the poor, that they were all loved by God too
3. He came to break down the walls between Jew and Gentile and show that all are God's children
4. He came to teach us that the essence of all the law is to love God and love one another
5. He came to teach that it is better to serve than to be served, to love rather than be loved, to give rather than to take, to act in peace rather than violence
6. He came to show us that God loves us, forgives us, wants us back, and will do anything for us
7. He came to show that religious rules are only a tool, not the goal, and anything that fails to serve God's ultimate purpose of loving God and loving one another should be dropped
8. He came to show us that death is not the end, that Satan has not won, but that God has defeated the devil and even death itself and we can share in that victory with Him
If I thought about this for longer than I will probably realize I missed something, but that's what comes to me off the top of my head.
