And your feet shod with the preparation of the gospel of peace (Ephesians 6:15).
In the armor of God described in Ephesians 6, the shoes seem somewhat mundane when contrasted to the more glamorous pieces. Yet, these shoes play a vital and indispensable part in the effective warfare of a Christian.
They are defined as the preparation of the gospel of peace, with the emphasis on preparation. Much could be said relative to the gospel (I Corinthians 15:14) with its focus on the substitutionary death (Isaiah 53:19), physical burial (Hebrews 2:14,15), and bodily resurrection (Acts 2:2936) of the Lord Jesus Christ. The Bible identifies the creation account as part of the gospels message (Revelation 14:6,7), as well as the promise of the eternal Kingdom (Revelation 11:1518). And no gospel message would be clear without a presentation of the true nature of sin and its awful consequences for the unbeliever (Romans 3:1023; II Thessalonians 1:79), or without an understanding of the anointed, incarnate Son of God (Isaiah 9:6; Acts 4:12).
The receiving of all these data requires preparation. Peter says that we must be always ready to give an answer [apologia] to every man (I Peter 3:15). Paul noted that he was set for the defense of the gospel (Philippians 1:17), and that we were to know how (we) ought to answer every man (Colossians 4:6) and to participate with him in the confirmation of the gospel (Philippians 1:7). This great work cannot be carried out by the wisdom of words (I Corinthians 1:17,18), or in any way be misunderstood as another gospel (Galatians 1:69) or some other way (John 10:111). Our feet must be shod with such solid preparation that we will not suffer injury when our feet are dashed against a stone (Psalm 91:12), and so that we can run, and not be weary; and . . . walk, and not faint (Isaiah 40:31).
