Passage
But let every one prove his own work: and so he shall have glory in himself only and not in another.
But let every one prove his own work: and so he shall have glory in himself only and not in another.
Galatians 6:2 Bear ye one another's burdens: and so you shall fulfil the law of Christ.
Galatians 6:3 For if any man think himself to be some thing, whereas he is nothing, he deceiveth himself.
Galatians 6:4 But let every one prove his own work: and so he shall have glory in himself only and not in another.
Galatians 6:5 For every one shall bear his own burden.
Galatians 6:6 And let him that is instructed in the word communicate to him that instructeth him, in all good things.
The verse centers on "prove", "shall", "glory", "himself", "only", and "another". It is saying that the verse draws attention to "prove" and "shall", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 3's "For if any man think himself to..." into verse 5's "For every one shall bear his own...", so "prove" and "shall" belong inside that flow. In Galatians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "prove" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
