How do we know that God predestines people?

Predestination is a crucial doctrine within the sovereign grace theology supported by biblical texts such as Romans 8:29-30, which states that those whom God foreknew, He also predestined to be conformed to the image of His Son. This indicates that God's love and choice were not random but intentional and eternal. The concept of predestination reflects God's sovereignty in salvation, affirming that it is He who determines beforehand those who will be saved and transformed to reflect Christ's image. Understanding this doctrine assures believers of God's unchanging plan and purpose in their lives.
