If you want to become a Christian, it’s not an accident. “No one can come to me unless the Father who sent me draws him.” (John 6:44)
You don’t have to be perfect to become a Christian. In fact, if you read the Bible, those who were the most messed up- Moses (murderer), David (murder, adulterer, terrible dad), Jacob (thief, coward), Rahab (prostitute), Peter (all talk, no follow up), Paul (murderer)- were the ones God used the most. Jesus said, “It’s not the healthy who need a doctor, but the sick. I have not come to call the righteous, but the sinners.” (Mark 2:17) The common denominator was choosing to follow him.
It’s actually very simple to become a Christian. You simply say (and mean), “Dear Jesus, please forgive me of my sins. I believe you died for me. Please come into my heart.”
“If you confess with your mouth, “Jesus is Lord”,and believe in you heart that God raised him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved.” (Romans 10:9-10)
