Ephesians 2:18

For through him, we both - Jews and gentiles. Have access - Liberty of approaching, by the guidance and aid of one Spirit to God as our Father. Christ, the Spirit, and the Father, the three-one God, stand frequently in the same order.

For through him we both have an access, That is, both Jews and Gentiles; the Arabic version reads, "we both factions": being made one, and reconciled unto God, and having the Gospel of peace preached to both, they have through Christ freedom of access and boldness in it: by one Spirit unto the Father: they may come to God as the Father of spirits, and of mercies, who has made their souls or spirits, and bestowed his mercies on them in great abundance; and as the Father of Christ, and as their God and Father in Christ: and the rather they should consider him in this relation to them, in order to command in them a reverence and fear of him; to secure a freedom and liberty in their approach to him; and to encourage an holy boldness, and a fiducial confidence in him; and to teach them submission to his will: and their access to him is "through" Christ, who has made peace for them, and atonement for their sins; who has satisfied law and justice, and brought in an everlasting righteousness for them; so that there is nothing lies in their way to hinder them; and besides, he takes them as it were by the hand, and leads them into the presence of his Father, and presents their petitions for them, on whose account they have both audience and acceptance with God: and this access is also "by one Spirit"; the "Holy Spirit", as the Ethiopic version reads; and who is necessary in access to God, as a spirit of adoption, to enable and encourage souls to go to God as a father; and as a spirit of supplication, to teach both how to pray, and for what, as they should; and as a free spirit to give them liberty to speak their minds freely, and pour out their souls to God; and as a spirit of faith to engage them to pray in faith, and with holy boldness, confidence, and importunity; and he is said to be "one", both with respect to the persons to and by whom access is had, the Father and Christ […]

Our access is by the Holy Spirit. Christ purchased for us leave to come to God, and the Spirit gives us a heart to come and strength to come, even grace to serve God acceptably. Observe, We draw nigh to God, through Jesus Christ, by the help of the Spirit.

For through him - Christ Jesus, we both - Jews and Gentiles, have access by one Spirit - through the influence of the Holy Ghost, unto the Father - God Almighty. This text is a plain proof of the holy Trinity. Jews and Gentiles are to be presented unto God the Father; the Spirit of God works in their hearts, and prepares them for this presentation; and Jesus Christ himself introduces them. No soul can have access to God but by Jesus Christ, and he introduces none but such as receive his Holy Spirit.

Translate, "For it is through Him (Joh 14:6; Heb 10:19) that we have our access (Eph 3:12; Ro 5:2), both of us, in (that is, united in, that is, "by," 1Co 12:13, Greek) one Spirit to the Father," namely, as our common Father, reconciled to both alike; whence flows the removal of all separation between Jew and Gentile.

For through him - That is, he has secured this result that we have access to God. This he did by his death - reconciling us to God by the doctrines which he taught - acquainting us with God; and by his intercession in heaven - by which our “prayers gain acceptance” with him. We both have access - Both Jews and Gentiles; see the notes at Rom 5:2. We are permitted to approach God through him, or in his name. The Greek word here - προσαγωγή prosagōgē - relates properly to the introduction to, or audience which we are permitted to have with a prince or other person of high rank. This must be effected through an officer of court to whom the duty is entrusted. “Rosenmuller,” Alt und neu Morgenland, in loc. By one Spirit - By the aid of the same Spirit - the Holy Spirit; see notes, 1Co 12:4. Unto the Father - We are permitted to come and address God as our Father; see the Rom 8:15, note 26, note.
