“Boasting” is pointing to something as the source of our identity and the grounds of our confidence. Galatians 6 teaches us that we can boast in vain (empty) things, or we can boast in the cross of Christ! If our identity and confidence comes from the cross, then Christ will transform our conduct toward one another, to make his churches beautiful communities of love and service.

Though Christians still experience sinful desires, the Holy Spirit has been given to wage war within us, restrain the flesh, and produce the fruit of godliness. We cannot defeat sin by our own effort, but the Spirit enables us to live the life we were remade to want. Rather than following the desires of the flesh, we are called to walk by the Spirit, keeping in step with him daily. He leads us through Scripture, prayer, conviction, and the ordinary means of grace—offering strength, guidance, and growth that comes from God, not ourselves.

True Christian freedom is not autonomy to indulge the flesh but liberation from sin to walk in love, as a new creation in Christ. Paul urges believers to purge all hindrances to that freedom—by obeying the truth of the gospel, searching diligently for sin, and embracing the offense of the cross. Our calling mirrors the Exodus: freed not by works, but by grace, we now submit our desires to God and fulfill the law through loving others. This scandalous freedom leads us to joyfully serve, because Christ served us first.
