Believing “in” Christ Jesus our Lord is not believing “of” him. Even the demons believe of him. In him is being “in” the vine, we are the branches. The sap of grace flows from the vine into us the branches. Being “in” Christ is experiencing him in an intimate way. Only those born again understand this. This is a true now and "being" mode. Not a wanting or having or doing mode. We only truly rest “in” him.
CERTAINLY resting in, being in Him is a crucial priority. . . . probably most crucial.
Nevertheless, WANTING ALL OF GOD . . . . in any sense, all that God would desire to place withinh one; meet with one, . . . . is also a worthy priority, choice.
