In Him we have redemption through His blood, the forgiveness of our trespasses, according to the riches of His grace which He lavished on us. In all wisdom and insight He made known to us the mystery of His will, according to His kind intention which He purposed in Him with a view to an administration suitable to the fullness of the times, that is, the summing up of all things in Christ, things in the heavens and things on the earth. In Him also we have obtained an inheritance, having been predestined according to His purpose who works all things after the counsel of His will, to the end that we who were the first to hope in Christ would be to the praise of His glory.” Ephesians 1:3-12. (Emphasis added).
Not only is the word “predestined” clearly and repeatedly stated, there are additional statements which support predestination. “He chose us in Him before the foundation of the world”. We have been predestined “according to His purpose who works all things after the counsel of His will”. His will is “the summing up of all things in Christ”.
Not only are there these clear statements of predestination, there is the emphasis of how predestination is “to the praise of the glory of His grace” and “to the praise of His glory”. In other words, God is glorified alone when He alone determines who is saved. As stated in the prior post, to the Arminian, salvation is a work of two parties. God gets the credit and glory for the “cross of Christ”, and man gets the credit and glory for “the free will of man” which chose Christ. However, to the Calvinist, salvation is the work of one party Who is God. God gets all the credit and all the glory.
