Galatians 5:1-2

Amplified Bible

Walk by the Spirit

5 It was for this freedom that Christ set us free [completely liberating us]; therefore keep standing firm and do not be subject again to a yoke of slavery [which you once removed].

² Notice, it is I, Paul, who tells you that if you receive circumcision [as a supposed requirement of salvation], Christ will be of no benefit to you [for you will lack the faith in Christ that is necessary for salvation].
