What does Ephesians 6:10 mean?

Verses 10 through 20 are a famous and well-used portion of Scripture. Paul wraps up his practical teachings with a series of analogies, comparing aspects of the Christian faith to the equipment carried by a soldier.

This verse introduces the overall motivation for Paul's instructions. Namely, this is strength, through the Lord, and of the Lord. Paul opened his letter with a prayer for the Ephesian Christians to receive wisdom and knowledge (Ephesians 1:15-23). Here, after discussing the real-world application of that wisdom, Paul notes that the believer does not rely on his or her own strength, but on the power of God to win victory in life's battles.

The following verses will offer an outline of each part of the metaphorical armor of God. Each piece connects to an area of spiritual life important for reliance upon God's strength. Paul's depiction of these components will conclude with a focus on prayer (Ephesians 6:18–20), again asking God for strength and success in battle. Only by relying on God, through these spiritual tools, can we overcome spiritual evil and succeed at living out God's will.

Paul personally saw himself as a spiritual warrior as well. In fact, he was often a prisoner of war, in a sense (Ephesians 6:20), yet still involved in the battle to reach others with the good news of Jesus.
