Which Lord Jesus Christ, (mentioned immediately before), or which God who is faithful, (mentioned immediately after, 1 Corinthians 1:9), shall confirm your habits of grace unto the end, approving himself the finisher of your faith, (you being not wanting in your duty and endeavour): so as either you shall not fall, or at least not totally and finally, but so as you shall rise again, and appear in the day of our Lord Jesus without blame, so as he will accept you as if you had never sinned against him.
