If you read my OP, you would realize that I believe in "a personal relationship with Jesus Christ" and indeed experience it. Reread the OP and you will see that the issue raised is that the Bible never uses the expression and indeed the texts commonly cited to defend this experience don't explicitly do so. More importantly, 3 out of 4 evangelical young people lose their faith in college precisely because they have never had such an experience t sustain them in times of doubt. They previously relied on confession of sin and faith in the Gospel and assumed, wrongly, that that automatically bestowed the indwelling Holy Spirit on them. For them, the Parable of the Prodigal Son, the Good Shepherd discourse, and stree on our status as "sons of God" amounts a head trip--just enough spirituality to inoculate them against the real thing! In my next planned post, I will finally identify theYour over thinking the simplicity of the concept. "My sheep hear my voice..." you either Know him intimately or you do not. These are not complicated theological concepts, but ones that are based on childlike faith. By trying to overcomplexify these things you are doing a disservice to the body. Your mind is thinking in carnal terms not in the Spiritual. Spiritually, we are sheep, he is the shepherd, Spiritually we are sons and daughters by adoption, And He is our Father to whom we cry "Abba, Father". He disciplines us as sons and daughters, not as bastards, he Loves us as his sons and daughters and we know his love. These are all "relational" concepts and very scriptural and literal and Spiritually discerned, a concept which you seem to be lacking if you cannot see nor defend this concept. The Problem is with you, not with concept of having a personal relationship with Christ, this whole post in fact is pointing to a deficiency in your own doctrine, a lack of Spiritual discernment.
I say this not to "put you down", but to get you rather to seek that which you are missing. Read James 4:1-10 carefully.
God Bless.
biblical solution to this problem.
