Ephesians 2:5-7 says,
"...and you, being dead in trespasses, he made alive together with Christ (by grace you have been saved), and he raised [you] together and seated [you] together in the heavenly places in Christ Jesus, in order that he might show in the coming ages the surpassing wealth of his grace in kindness toward us in Christ Jesus."
The very next verse following this long sentence is this: "for by grace you have been saved through faith, and this is not from you, it is the gift of God" (v. 8).
What did Paul want his readers to understand about the "surpassing wealth" or "riches" of God's grace? Well, first of all, that for us who have been saved by faith in God's Son, the ages to come are going to be a showcase of the super-abundance of His favor (grace) and kindness toward us in Christ. It is through Jesus Christ that the ages to come in eternity will display how much of an abundance of favor and kindness we have received from God. He died on the cross, the perfect Savior, God in human flesh, paid the penalty for our sinful crimes, rose from the dead and lavished this favor upon us.
All the abundance of favor, the riches of God's kindness and mercy, His never ending, age-enduring, ever-bestowing love is ours in Christ. Jesus is truly awesome! God our Father is truly loving! The Holy Spirit is truly our Comforter!
We Christians have a lot to be thankful for and a lot to look forward to. May all the glory be to God and to the Lamb!
