This is the 17th in a series of articles on the Trinity, excerpted from “What Every Christian Should Know About the Trinity,” available through Amazon and other booksellers.
Let’s consider the wonderful doctrine of God as Father of the church – specifically, as the Father of everyone who receives His Son, Jesus Christ, by faith and thus is adopted into God’s family.
The Bible speaks of adoption as an act of God making born-again believers members of His family. As in first-century Roman culture, all former relationships of the adopted child are severed, and the adoptee is made a full-fledged member of his or her new family under the father’s authority, and with the full privileges and responsibilities of an adult
For Christians, then, no longer does the evil one hold his servants captive, in spiritual blindness, alienated from God, and destined for outer darkness. Christ has come to our rescue, redeeming us from the slave market of sin and joyfully welcoming us into the Father’s family as Jesus’ coheirs in His everlasting kingdom.
Adoption into God’s family is part of the Father’s predestined plan for everyone who believes. It is inextricably bound to all other elements of salvation, spanning from eternity past in foreknowledge to eternity future in glorification. As a consequence, we may rest assured of our salvation, for just as a Roman father could not disown an adopted son, God is faithful to His promise to conform us to the image of His eternal Son.
