Romans 5:2

διʼ οὗ καὶ : through whom also. To the fact that we have peace with God through our Lord Jesus Christ corresponds this other fact, that through Him we have had (and have) our access into this grace, etc. προσαγωγὴ has a certain touch of formality. Christ has “introduced” us to our standing as Christians: cf. Ephesians 2:18; 1 Peter 3:18. τῇ πίστει : by the faith referred to in Romans 5:1. Not to be construed with εἰς τὴν χάριν ταύτην : which would be without analogy in the N.T. The grace is substantially one with justification: it is the new spiritual atmosphere in which the believer lives as reconciled to God. καυχώμεθα, which always implies the expression of feeling, is to be co-ordinated with ἔχομεν. ἐπʼ ἐλπίδι τῆς δόξης τοῦ θεοῦ : on the basis of hope in the glory of God, i.e., of partaking in the glory of the heavenly kingdom. For ἐπʼ ἐλπίδι, cf. Romans 4:18 : the construction is not elsewhere found with καυχᾶσθαι.
