Passage
The grace of our Lord Jesus Christ [be] with your spirit, brethren. Amen.
The grace of our Lord Jesus Christ [be] with your spirit, brethren. Amen.
Galatians 6:16 And as many as shall walk by this rule, peace upon them and mercy, and upon the Israel of God.
Galatians 6:17 For the rest let no one trouble me, for *I* bear in my body the brands of the Lord Jesus.
Galatians 6:18 The grace of our Lord Jesus Christ [be] with your spirit, brethren. Amen.
The verse centers on "Spirit", "grace", "lord", "jesus", "christ", "brethren", and "amen". It is saying that salvation is received as God's gift through faith, so boasting is pushed out by the wording itself.
The prior verse says "For the rest let no one trouble...", giving immediate footing for "Spirit" and "grace". In Galatians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "Spirit" and "grace" with trust shaped by these words, not by a vague optimism outside the passage.
