Ephesians 6:11-12 we are told to put on the whole armor of God. Many Christians are truthful. They have their heart free of sin, they are sure of their salvation, they rightly use the Word of God. But they are shoeless—they are not prepared to share the gospel. Those who do not advance the cause of the gospel are stationary soldiers; any evangelistic movement is too painful for them. If they are not seeking to save the lost, they are not taking ground for the kingdom of God. Paul climaxed his admonition to the Ephesians by highlighting what the battle is for. He pleads with them to pray for him to have boldness to reach out to the unsaved, citing his moral responsibility (see vs. 20).
