We are chosen by God. In God's grace we are redeemed and secured in Christ. God came for us and made us His own. And now we know that we are His. For all eternity we are in Christ.
Once we were all lost in sin, but God provided a divine plan for saving His people. He placed us at the forefront of His plan. It was by His rich mercy (2:4; Ps. 103:8-12). His great love (2:4; John 3:16; Rom. 5:8), and His marvelous and wonderful grace (2:5; 1 Tim. 1:13-14) together to provide a free gift (2:8; Rom. 6:23) received by faith (Rom. 10:17).
When God raised Christ from the dead, he also raised up all believers together with Him, and when God placed Christ at His right hand in the heavenly places, He also glorified them in and with Him–And made us sit together in heavenly places in Christ Jesus. Sanctified souls sit in heavenly places. Thus, they are exalted to reign with Him; they sit upon the throne with Christ.
Thanks be to God for his great love, mercy and "marvelous, wonderful grace."
