Adoption

the giving to any one the name and place and privileges of a son
who is not a son by birth.

(1.) Natural. Thus Pharaoh's daughter adopted Moses (Ex.
2:10), and Mordecai Esther (Esther 2:7).

(2.) National. God adopted Israel (Ex. 4:22; Deut. 7:6; Hos.
11:1; Rom. 9:4).

(3.) Spiritual. An act of God's grace by which he brings men
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 peculiar love (John 17:23;
Rom. 5:5-8), a spiritual nature (2 Pet. 1:4; John 1:13), the
possession of a spirit becoming children of God (1 Pet. 1:14; 2
John 4; Rom. 8:15-21; Gal. 5:1; Heb. 2:15), present protection,
consolation, supplies (Luke 12:27-32; John 14:18; 1 Cor.
3:21-23; 2 Cor. 1:4), fatherly chastisements (Heb. 12:5-11), and
a future glorious inheritance (Rom. 8:17,23; James 2:5; Phil.
3:21).
