The eyes of your understanding being enlightened; that ye may know what is the hope of his calling, and what the riches of the glory of his inheritance in the saints,
Paul specified two particular areas of divine knowledge which God desires for us – 1) the hope of His calling, this points forward to the future and 2) the riches of the glory of His inheritance in the saints, a coming to a realization of all that God has in store for us.
Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.
The “earnest of our inheritance” is the Holy Spirit, which is the guarantee that we will receive all that was promised to us because of salvation. As soon as we are saved, the Holy Spirit begins to reveal to us some of the riches that are ours in Christ.
Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ:
Paul begins by calling on all who know God to bless Him, we bless God by praising and worshipping Him. God blesses us with all spiritual blessings, those are treasures that are immaterial (peace, joy, rest, etc), invisible (protection, security, stability, etc), and imperishable (heaven, inheritance, etc).
2 Corinthians 8:9
For ye know the grace of our Lord Jesus Christ, that, though he was rich, yet for your sakes he became poor, that ye through his poverty might be rich.
Christ was so generous that He gave all He had for our sakes that we, through His poverty, might become eternally rich.
That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel:
Converted Gentiles and Jews enjoy equal privileges in a church and in Heaven. Gentiles and Jews are fellow heirs, as they both are heirs of God and joint heirs of God, are of the same body, they share a position of equality in a church, and are fellow partakers of the promise of Christ through the gospel, they both receive the Holy Spirit at the moment of salvation.
He that overcometh shall inherit all things; and I will be his God, and he shall be my son.
God made the promise to the overcomer, they will inherit all that God has and they will have a close, intimate relationship with Him.
2 Corinthians 6:10
As sorrowful, yet alway rejoicing; as poor, yet making many rich; as having nothing, and yet possessing all things.
There may be occasional sorrow with ministry, but there is always rejoicing. Paul may have had sorrow over the rejection of the gospel message, over the failures of God’s people, and over his own shortcomings, but when he thought of the Lord, and of the promises of God, there was always great cause to look up and rejoice.
1 Corinthians 3:21-23
Therefore let no man glory in men. For all things are yours; Whether Paul, or Apollos, or Cephas, or the world, or life, or death, or things present, or things to come; all are yours; And ye are Christ’s; and Christ is God’s.
Paul stated that no one should boast in men. And as far as true servants of the Lord are concerned, we should not boast that we belong to them but rather realize that they all belong to us because of Christ.
And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.
Membership in God’s family brings privilege, as all of God’s children are heirs of God. An heir is one who eventually inherit their father’ estate. Because of adoption, all that the Father has is ours. We have not yet come into the possession and enjoyment of it all, but nothing can prevent our doing so in the future.
For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
When we are born again, we are not placed into a position of a servant or slave, shadowed by the fear of punishment. Rather, we receive the spirit of adoption and are placed in God’s family as a mature son.
