Without strength; utterly unable to help or redeem ourselves. In due time; some read it, according to the time, and refer this clause to the foregoing words, making this to be the sense: When we were weak in time past, or in the time of the law, before grace appeared, then Christ died, &c. Others rather refer it to the following words, and so our translation carries it, that in due time, i.e. in the fulness of time, as Galatians 4:4, or in the time that was before decreed and prefixed by the Father. The Scripture every where speaks of a certain season or hour assigned for the death of Christ: see Matthew 26:45 1 Thessalonians 8:20, 1 Thessalonians 12:27 17:1. Christ died for the ungodly; i.e. for the sake, or instead of, such as were enemies to God, \as Romans 5:10\ and so could deserve no such favour from him.
