I have found that 'deeper' fellowship has to do with FIRST being "born again" by having the Lord Jesus in our heart and life (John 3; John 14;etc.); then one needs to be in communion with Him and the Father every day and ALL day ---making Him your best Friend. I have been walking and talking with Him for over 60 years, and it is a wonderful blessing and comfort. God says to "bring into captivity every thought to the obedience of Christ" (2 Cor. 10:5). Walking and talking with Him is precious to a "born again" believer (who stays in communion, avoiding worldly ways). It is a choice --living for Christ or for self and the world's ways!
