Spirit Now Indwelling

...as the bond of union to God, the Spirit indwells all who believe as the Spirit of the Lord Jesus Christ. This is a development of epochal proportions. The Spirit who was present and active at Christ's conception as the head of the new creation, by whom he was anointed at baptism (Jn. 1:32-34), who directed him throughout his temptations (Mt. 4: 1), empowered him in his miracles (Lk. 11 :20), energized him in his sacrifice (Heb. 9:14), and vindicated him in his resurrection (1 Tim. 3: 16; Rom. 1 :4), now indwells disciples in this specific identity. This is the meaning of our Lord's words, otherwise impossible to comprehend: 'It is for your good that I am going away' (Jn. 16:7)
