Matthew Henry on Ephesians 2:14-18

Jesus Christ made peace by the sacrifice of himself; in every sense Christ was their Peace, the author, centre, and substance of their being at peace with God, and of their union with the Jewish believers in one church. Through the person, sacrifice, and mediation of Christ, sinners are allowed to draw near to God as a Father, and are brought with acceptance into his presence, with their worship and services, under the teaching of the Holy Spirit, as one with the Father and the Son. Christ purchased leave for us to come to God; and the Spirit gives a heart to come, and strength to come, and then grace to serve God acceptably.
