What does it mean to be predestined by God?

Being predestined by God indicates His sovereign decision to choose certain individuals for salvation, as explicitly stated in Ephesians 1:5, where it says we have been predestined to adoption as God's children. This terrifying doctrine underscores God's control over our salvation, affirming that it is His will rather than our works that determines our eternal destiny. Such truth reinforces the beauty and assurance of salvation, ensuring that believers can rest in the fact that their salvation was established in the divine will of God long before they were born.
