A right and good and vital relationship with God (in all its many dimensions) is the primary point/purpose of true Christianity (the Gospel, salvation). That means a right and good and vital way of habitually relating to God in trust, repentance, dependence, allegiance, love and obedience.
John 14:21, 23-24a; 15:14
"Christ is our best friend, and ere long will be our only friend. I pray God with all my heart that I may be weary of everything else but converse and communion with him." -- John Owen
