This trusting is not just believing about Christ, but actually belonging to Him. “And if you are Christ’s”—are you? Do you belong to Christ by faith? Are you immersed into Him? Have you put Him on like a garment, covering you? Have you entrusted your life into Him?
If so, then you are no longer a little child under the tutor of the Law, but you are a full-grown “heir according to promise.” In Christ, you inherit the eternal blessings of God, being right with Him, being in His kingdom, having His Spirit to guide you through life.
Do you belong to Christ?
