Adam Clarke on 1 Corinthians 15:57

But thanks be to God - What the law could not do, because it is law, (and law cannot provide pardon), is done by the Gospel of our Lord Jesus Christ: he has died to slay death; he has risen again to bring mankind from under the empire of hades. All this he has done through his mere unmerited mercy; and eternal thanks are due to God for this unspeakable gift. He has given us the victory over sin, Satan, death, the grave, and hell.
