What does the Bible say about adoption?

Adoption is a significant biblical doctrine that emphasizes the transformative relationship between believers and God. In 1 John 3:1, John marvels at the love bestowed upon us by God, declaring that we are called the children of God. This imagery of adoption reflects a deep familial bond, contrasting our natural state as children of Adam, estranged from God, to being welcomed into His family through grace. The New Testament repeatedly affirms this theme, associating adoption with the privileges and love surrounding our union with Christ.
