Paul rebuked the Galatian Churches for attempting to be saved by things that God only intended for the nation of Israel, such as circumcision. Therefore, Paul said,
“For we through the Spirit eagerly wait for the hope of righteousness by faith. For in Christ Jesus neither circumcision nor uncircumcision avails anything, but faith working through love” (Galatians 5:5-6).
The Galatians missed the point of circumcision. In circumcision something was cut away. That foreshadowed the cutting away that we experience in Christ, which happens during baptism when the Lord cuts away our sin (Colossians 2:11, 12).
No, we do not find hope in things God only intended for Israel as matters of salvation, but we find hope in the Spirit by being in Christ.
Are you in Christ? Have you been baptized?
