The "Spirit of God bears witness with our spirit" that we are actually the children of God ... and while socialization is possible with one who is not born again ... true fellowship is impossible because the Spirit that resides in the Word is not personally present in a person ... even though Scripture may be recited.
This true fellowship in the Word is an amazing reality and difficult to describe ... but is similar to an unspoken language ... a form of communication in which only genuine born again believers can participate ... based on the principles of the Word of God ... but does not always require communicating with words ... because the Holy Spirit is present to provide a lot of understanding ... even when very little is said.
