What does the Bible say about adoption and salvation?

Adoption is a profound theme throughout Scripture, representing God's unilateral decision to select individuals from Adam's fallen race as His own. According to 1 John 3:1, we are called the children of God due to the immense love the Father has bestowed upon us. This act of adoption is legally binding and instituted according to God's established justice, indicating that nothing can come between the holy God and those He adopts. The process is initiated entirely by the adoptive parent, God Himself, who, motivated by love, fulfills all legal requirements through the sacrifice of His Son, Jesus Christ, ensuring those adopted can stand righteous before Him.
