12 that at that time you were without Christ, being aliens from the commonwealth of Israel and strangers from the covenants of promise, having no hope and without God in the world. 13 But now in Christ Jesus you who once were far off have been brought near by the blood of Christ. (Ephesians 2:12–13, NKJV)
The Gentiles were not in a covenant relationship with God through the Law of Moses. Only Israel was under that law, and were the people of the covenant (Deut. 5:2-3). That is why Paul speaks of the Gentiles as “having no hope and without God in the world” (v. 12). This is an apt description of the spiritual status of all who are lost in sin: Aliens, without God, without hope, and without an inheritance (see Eph. 2:1-3). But, “in Christ Jesus” all that changes. In Christ, one has a living hope (1 Pet. 1:3). In Christ, the sinner is a new creation (2 Cor. 5:17). Through faith in Christ Jesus, lost sinners are saved, and become children of God (Gal. 3:26; 4:5-7). The alien sinner comes into a saved relationship with God by putting on Christ, which occurs when the sinner is “baptized into Christ” (Gal. 3:27). The blood of Christ – His death for our sins – makes it possible for us to be reconciled to God (Eph. 2:16). It washes away our sins when we are baptized into Christ (Rom. 6:3-4; Acts 22:16). No longer live without God and without hope. By faith, be baptized into Christ and be saved. “Why are you waiting?” (Acts 22:16)
