Being confident of this very thing, that he which has begun a good work in you will perform it until the day of Jesus Christ:
He had one great historical instance to commend his theological inference. For he knew, with all the depth and intensity of a late and reluctant realization, that the whole history of his own people had been one vast illustration of the truth on which he relied. In them, far back, in the very childhood of the race, God had begun a good work: patriarchs, psalmists, prophets had by faith been confident that He would perform it: and He had actually performed it until the day of Jesus Christ, until His first coming. From the call of Abraham to the Incarnation one purpose had been steadfast, one work had moved on a line determined from the beginning — all that vast period, with its surprises and disasters, its restless shirtings, its immeasurable contrasts, had been spanned by one dominant conception — through all that seemed so disorderly and aimless there had sped the evolution of one supreme design — from first to last one thought held good, one will pressed on — and He who came at last could look back across the centuries to that majestic, solitary form upon the far-distant watch-tower, and could declare — "Your father Abraham rejoiced to see My day: and he saw it and was glad."
(J. Paget, D. D.)
