How do we know that predestination is true according to the Bible?

Predestination is a core tenet of Reformed theology, rooted deeply in scripture. Romans 8:29-30 explicitly teaches that those whom God foreknew, He also predestined to be conformed to the image of His Son. This indicates that before the foundation of the world, God chose certain individuals to enter into a saving relationship with Him, effectively orchestrating their salvation according to His will. Ephesians 1:4-5 also states that God chose us in Him before the foundation of the world, predestining us for adoption as His children. This biblical foundation offers assurance that salvation is not based on human decision, but rather on God's sovereign and unchangeable purpose, which brings glory to Him and offers believers a profound security in their salvation.
