Even though this is the modus operandi of the church today (for the most part) I think God does honor to some extent the person who has called on his name in this limited way. I think they comprise the people who say they've been a Christian all their life but who then enter into a truly spiritual relationship with God later in life, usually after a severe trial of life. It's the difference between being a 'water only' believer, and a 'water and Spirit' believer (John 3:5-6, Galatians 4:29). Lot's of water only salvations out there. God is busy bringing them into the Spiritual part of salvation.
