What does the Bible say about God's preparation for salvation?

According to Ephesians 1:4-5, God chose us in Christ before the foundation of the world, highlighting that our salvation is not accidental; it was purposed. This great supper represents God's provision for salvation, which is fully realized in Christ. The preparation of this feast, salvation itself, is rooted in the eternal decree of God who, out of His infinite love, predestined His people to be holy and without blame through Jesus Christ. Thus, every aspect of our salvation, from its divine origin to its execution in history, underscores that it is entirely God's doing.
