Have you ever asked yourself why you rebelled against being a "P.K." as you grew older and decided you didn't want anything more to do with Jesus?
Only you can answer this, of course - but I suspect that most of your reasons didn't really have very much to do with Jesus Christ. For example, some people leave their faith behind as they grow older simply because they yearn to be independent - that is, they want to run their own lives. They don't want their parents to tell them what to do any longer - nor do they want God telling them. Instead, they want to make their own decisions - and that often means going in the opposite direction from their parents. Was this true of you?
In other words, I seriously doubt if you investigated the claims of Christ and decided they weren't valid. Instead, you turned away from Christ for emotional reasons: You simply didn't want anything further to do with your parents or their beliefs.
But listen: God has never stopped loving you, and He yearns for you to turn back to Him and receive Christ into your life. Jesus' promise is for you: "Come to me, all you who are weary and burdened, and I will give you rest" (Matthew 11:28). By a simple prayer of faith confess your sins to God and ask Christ to come into your life - and He will.
