Adoption …what does the Bible say about it?
Adoption is the giving to any one the name and place and privileges of a son or daughter who is not a son or daughter by birth.
SPIRITUAL ADOPTION. An act of God’s grace by which he brings people into the number of his redeemed family, and makes them partakers of all the blessings he has provided for them. Adoption represents the new relations into which the believer is introduced by justification, and the privileges connected therewith, viz., an interest in God’s special love (John 17:23; Romans 5:5-8), a spiritual nature (2 Peter 1:4; John 1:13), the possession of a spirit becoming children of God (1 Peter 1:14; 2 John 4; Romans 8:15-21; Galatians 5:1; Hebrews 2:15), present protection, consolation, supplies (Luke 12:27-32; John 14:18; 1 Corinthians 3:21-23; 2 Corinthians 1:4), fatherly chastisements (Hebrews 12:5-11), and a future glorious inheritance (Romans 8:17, 23; James 2:5; Philippians 3:21).
