The picture that Paul paints with his words here is an extremely beautiful one. God has blessed us abundantly. He has blessed us with all spiritual blessings in heavenly places in Christ. He has chosen us before the foundation of the world. He has predestinated us (that is all who respond to His great grace) to the adoption of children. He has given us redemption and forgiveness of sin through the blood of Christ. He has make know to us the mystery of His will, which is the gathering of all things together in one... that is in Christ.
The real center of all the purpose of God is Christ. Look at the importance that Paul gives this centrality of Christ
Verse 3 “all spiritual blessings in Christ.”
Verse 4 We are “chosen in Him.”
Verse 5 “Unto the adoption of Children by Jesus Christ.
Verse 6 We are accepted in the beloved
Verse 7 “In whom we have redemption.
Verse 8 “wherein He has abounded toward us in all wisdom and prudence
Verse 9 The description of God’s purpose to “make known to us the mystery of His will
Verse 10 That purpose was to gather all things together in one... In Christ
Verse 11 “In whom also we have obtained an ineritance.”
Verse 12 “That we who first trusted in Christ should be to the praise of His glory.”
We simply cannot stress too strongly the importance of being in Christ.
We have obtained an inheritance but we shall not fully receive it in this life. It is reserved in heaven for us. (1 Peter 1:4). Our inheritance is double barreled in that we have the best of life now (John 10:10) and then an inheritance that does not fade away reserved in heaven for us. Now we do not here receive the solution to all of our problems instantaneously... but we do receive the strength to solve them.
All Christians should be to the praise of His glory. But Paul is specifically speaking of Jews in this verse. They have had the advantage of being close to God, they expected the coming of the Messiah... now they ought to be ready. The same thought would apply to us today. We have been promised the return of Jesus, we ought to be ready.
