I came across these comforting words yesterday when reading Motyer’s comments on Philippians 1:6 (…being confident of this, that he who began a good work in you will carry it on to completion until the day of Christ Jesus. NIV)
Salvation would be a wretchedly unsure thing if it had no other foundation than my having chosen Christ. The human will blows hot and cold, is firm and unstable by fits and starts; it offers no security of tenure. But it is the will of God that is the ground of salvation. No one would be saved had not the Lord been moved by his own spontaneous and unexplained love to choose his people before the world was, and, at the decisive moment, to open our hearts to hear, understand and accept ‘the word of truth, the gospel of your salvation’. This, then, is assurance: God has willed my salvation.
