Ephesians 6:10 Meaning and Explanation

Paul says 'finally' and gathers everything into one charge: be strong. But he immediately tells us where that strength is found. It is in the Lord, and in the power of his might. The order matters, because Paul is not asking us to summon courage from our own reserves. He points us outside ourselves to a strength we receive rather than produce.

He even stacks the words, power and might, to make the source unmistakable. This is the same mighty strength that raised Christ from the dead (Ephesians 1:19-20), now made available to His people. So the command to be strong is really an invitation to lean. When we feel small before what we face, Paul does not tell us to try harder; he tells us whose strength to draw on. We are strong only in the One who is strong for us.

That opening word finally gathers the whole letter into a single stance. Everything Paul has unfolded, the riches of grace, the one new body, the calling to walk worthy, now braces for opposition, and his first counsel is not a weapon but a posture: be strong in the Lord. The Greek is passive in force, be strengthened, be made mighty, receiving power rather than mustering it. It echoes the ancient charge to Joshua on the edge of a hostile land, be strong and of a good courage, for the Lord thy God is with thee. The strength was never in the arm that held the sword but in the presence that went beside it. So here. We do not enter the fight to see if God will show up; we enter because He already has.
