We praise God because He has given us an eternal in Christ. In the NIV, verse 11 says: “In Him” – in Christ – “we were also chosen, having been predestined according to the plan of Him who works out everything in conformity with the purpose of His will.” The word for “predestined” is the same word used in verse 5, which speaks of our being “predestined …to be adopted” as His sons and daughters through Jesus Christ.” But a more literal translation of the first part of verse 11 would be: “In Him we have obtained [or gained] an inheritance” or “In Him we were made heirs.” This inheritance, says Church Swindoll, is “an eternal, irrevocable inheritance grounded in (God’s) sovereign choice and predestined according to His will” (Swindoll’s Living Insights New Testament Commentary: Galatians and Ephesians, 170)…
We praise God because, when we believed in Christ, He put the seal of the Holy Spirit on us. He gave us the Holy Spirit as a mark or seal of His ownership and of our new identity in Him.
The verb “to seal” (sphragizo in Greek) means “to mark as secure.” In Bible times, a seal was a sign of ownership or authenticity. A king or other ruler would put a seal on a document to show it was official. (See Esther 3:12; 8:8, 10, for example). The stone over the entrance to the lion’s den into which Daniel was thrown for disobeying the law against praying to anyone except the king, was sealed with the king’s ring along with the rings of his nobles, as the stamp of the king’s authority (Daniel 6:17).
So, too, the tomb where Jesus was laid after His crucifixion was, the Jewish leaders hoped, made secure by putting a seal on the stone over the entrance to the tomb (Matthew 27:66). But neither the stone with its seal nor the Roman guard at the tomb were enough to prevent Jesus from “busting out” on Easter morning!
