What does the Bible say about the adoption of children by Jesus Christ?

The adoption of believers as children of God is a profound biblical truth, grounded in the sovereign grace of God. Ephesians 1:4-5 states that God chose us in Christ before the foundation of the world, predestining us to be adopted as His children according to His will. This action reinforces the idea that our relationship with God is not based on our merit but solely on His grace. Through Christ's redemptive work, we who were once strangers and aliens are brought into the household of God, enjoying all the privileges as His beloved children.
