“…being predestinated according to the purpose of Him that worketh all things after the counsel of His own will.” – Ephesians 1:11

The predestination of everyone of God’s people was arranged at the eternal council, where God’s will sat as the sovereign umpire and undisputed president. There was it said of each redeemed one, “At such an hour I will call him by My grace, for I have loved him with an everlasting love, and by My lovingkindness will I draw him.” There was it originated when the peace-speaking blood shall be laid to that elect one’s conscience, when the Spirit of the living God shall breathe joy and consolation into his heart. There was it settled how that chosen one should be “kept by the power of God through faith unto salvation;” and there was it determined and settled by two immutable things, wherein it is impossible for God to lie, that every one of these should be eternally saved, beyond the shadow of a risk of perishing. The apostle Paul was not like some preachers, who are afraid to say a word about the everlasting council, for he says in his epistle to the Hebrews-“God willing more abundantly to show unto the heirs of promise the immutability of His council, confirmed it by an oath.” Now, you hear some talk about the immutability of the promise: that is good. But the immutability of God’s counsel, -that is to fathom to the very uttermost the doctrines of grace. The council of God from all eternity is immutable; not one purpose has He ever altered, not one decree has He ever changed, He has nailed His decrees against the pillars of eternity, and though the devils have sought to rend them down from the posts of His magnificent palace, yet, saith He, “have I set My king upon My holy hill of Zion;” the decree shall stand; I will do all My pleasure. Thy counsels of old are faithfulness and truth. Thou, Lord, in the beginning hast made the heavens and laid the foundations of the earth, Thou hast determined Thy plans and purposes, and they stand fast for ever and ever. ~ C.H. Spurgeon
