Romans 8:29 For those whom he foreknew he also predestined to be conformed to the image of his Son, in order that he might be the firstborn among many brothers. And those whom he predestined he also called, and those whom he called he also justified, and those whom he justified he also glorified.
Psalms 1:6 for the LORD knows the way of the righteous, but the way of the wicked will perish.

2 Timothy 2:19 But God’s firm foundation stands, bearing this seal: “The Lord knows those who are his,” and, “Let everyone who names the name of the Lord depart from iniquity.”
Revelation 13:8 and all who dwell on earth will worship it, everyone whose name has not been written before the foundation of the world in the book of life of the Lamb who was slain.
Ephesians 1:5 he predestined us for adoption to himself as sons through Jesus Christ, according to the purpose of his will,
Ephesians 1:11 In him we have obtained an inheritance, having been predestined according to the purpose of him who works all things according to the counsel of his will,
Predestination can be easy or hard to understand. I think it is easier when you become saved, born again, and made new. It is hard as concrete to understand apart from believing in God, Jesus Christ, and the work that was done on the cross for our redemption, salvation, and forgiveness. It is hard to fully understand God’s omnipresence, omnipotent, and omniscience. All-knowing, all-powerful, all presence, Creator, alpha and omega, beginning and end, all truth, righteous, Holy, is our God. If possible to say, eternal past and eternal future. Before the foundation of creation, He predestines to call us and for us to be conformed to the image of Jesus Christ. Satan will put doubts into our hearts and minds. He will lead us to believe God can’t or won’t or just plain doesn’t have any idea what He is doing, or that if He does, He certainly won’t do it for the likes of us. But, He did and certainly does. He already knows who will, or won’t, surrender to His calling of repentance and belief, trust, and hope in Jesus Christ. He knows who will harden their hearts and those who will humbly surrender to His plan and purpose of redemption. He has prepared a place for both. To those who harden their hearts, He has prepared eternal Hell and forever separated from Him. To those who humbly surrendered He has prepared eternal heaven and forever present with Him.
If you find predestination hard to understand, yield to Him first, then allow His word to begin to give you a glimpse of His will, purposes, and plans. Certainly, we will only see glimpses of this but what we see will over-shadow all doubts and fill our hearts, minds, and souls with peace and assurance.
