Where is the page in Scripture that says Jesus knew for a fact that he would rise again?

Sure Jesus knew before hand, He also knew his brother Satan like him has the ability to obey God or do his own thing. Jesus could have lived forever on earth. His body was perfect. and he did not sin,But he gave his perfect body up for you. Jesus while on earth had an opportunity to give messages from God of hope and freedom from sin once and for all time. Does that mean anything to you? Jesus brought the dead back from the grave and healed blind,deaf,lepers,lame,all kinds of things. He did it to try to convince you that God loves you. We base our calender on the life of Jesus. we have millions of Church's around the world. If Jesus was a ping fad why would his life still be as loved to day as it was 2000 years ago? A bunch of Idiot atheists in this forum making fun of God will one day have to give an accounting of themselves to God but even then Thanks be to Jesus,they will have a redeemer also.
