Jesus Christ lived 2000 years ago and claimed to be the Son of God. He said, “I am the way, the truth, and the life. No one comes to the Father except through me.” (Read it in John 14:6.) That means everyone isn’t going to heaven, as you may have heard. Only those who believe Jesus is who he claimed to be will live in heaven forever.
The bottom line is we were born rebels. We naturally want our own little kingdom, our own selfish way, but God calls that sin. As Jesus said, life and truth are with him. We can’t have that and sin too. So Jesus paid the price for our sin with his life and death on a cross.
Because that price has been paid, we can have life and peace with God when we surrender control of our lives to him. “Because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved… Everyone who believes in him will not be put to shame” (Romans 10:9,11).
