Coming to accept and know Jesus is easy. Saying a simple prayer, like:
"Jesus, I recognize that I am a sinner in need of a savior. I am asking for you to come into my heart and wash away all my sins. In Jesus' name."
It is just that simple.
The thief on the cross who recognized that his time on earth was coming to a sudden end realized he too needed a savior. His simple prayer (Lord, remember me... Luke 23:42-43) was from the heart and that is the key. A simple prayer has to come from the heart and you have to mean it.
