But thanks be to God; - See the notes at Romans 7:25.
Which giveth us the victory - Us who are Christians; all Christians. The victory over sin, death, and the grave. God alone is the author of this victory. He formed the plan; he executed it in the gift of his Son; and he gives it to us personally when we come to die.
Through our Lord Jesus Christ - By his death, thus destroying the power of death; by his resurrection and triumph over the grave; and by his grace imparted to us to enable us to sustain the pains of death, and giving to us the hope of a glorious resurrection; compare the note at Romans 7:25; Romans 8:37.
