Which he wrought in Christ, when he raised him from the dead, and set him at his own right hand in the heavenly places,
Which - `working.'
In Christ - the 'first-fruits' of the resurrection, our Head.
When he raised him - `in that He (the Father) raised Him.' The raising of Christ is not only an earnest of our bodies being hereafter raised, but has a power in it involving (by virtue of our living union with Him, as members with the Head) the resurrection spiritually of the believer's soul now, consequently of his body hereafter (Romans 6:8-11; Romans 8:11). The Son, too, as God (though not as man), had a share in raising His own human body (John 2:19; John 10:17-18); also the Holy Spirit (Romans 1:4; 1 Peter 3:18).
Set him, х ekathisen (G2523)] - 'made Him sit.' The glorious spirits stand about the throne, but they do not sit at God's right hand (Psalms 110:1; Hebrews 1:13), where He remains until all His enemies have been put under His feet (1 Corinthians 15:24). Being appointed to 'rule in the midst of His enemies' during their rebellion (Psalms 110:2), He shall resign His commission after their subjection (Pearson) (Mark 16:19; Hebrews 1:3; Hebrews 10:12); then He, as God-man, shall reign forever and ever.
In the heavenly places (Ephesians 1:3; Ephesians 4:10). As Christ has a literal body, heaven is not merely a state, but a place; and where He is, there His people shall be (John 14:3: cf. Ephesians 1:11; 7:56).
