Ephesians 6:10

As Paul reaches the closing exhortation of his letter, he sounds a call to strength: "be strong in the Lord, and in the power of his might." The word "Finally" signals that he is gathering everything toward a climax. And the strength he calls for is not self-generated. Twice he locates its source outside ourselves -- "in the Lord" and "in the power of his might." The believer is not told to summon courage from within or to grit their teeth and try harder. They are told to draw on a strength that belongs to God and is made available to those who are in Him.

This is deeply freeing. The challenges Paul is about to describe -- spiritual conflict against unseen powers -- are far beyond human ability to face alone. If the believer had to rely on personal strength, the situation would be hopeless. But the call is to be strong in the Lord, to lean on His power rather than our own. The same mighty power that raised Christ and that works within us, mentioned earlier in the letter, is the power we are to rely on now. For the reader, this verse sets the right starting point for facing any battle. Before any weapon is named, the foundation is laid: real strength comes from God. We do not face life's struggles in our own resources but in His might, and that makes all the difference.
