Ephesians 6:15-16

15 And having shod your feet in preparation [to face the enemy with the firm-footed stability, the promptness, and the readiness produced by the good news] of the Gospel of peace.

Our feet are stabilized by the Gospel. The Gospel is the Word of our Father and the Word of our Father is Jesus.

And the Word (Christ) became flesh (human, incarnate) and tabernacled (fixed His tent of flesh, lived awhile) among us; and we [actually] saw His glory (His honor, His majesty), such glory as an only begotten son receives from his father, full of grace (favor, loving-kindness) and truth. John 1:14

Therefore He is able also to save to the uttermost (completely, perfectly, finally, and for all time and eternity) those who come to God through Him, since He is always living to make petition to God and intercede with Him and intervene for them. Hebrews 7:25

Our feet are stable because our Lord and Savior ever lives to intercede for us so that we are saved perfectly, completely, finally, and to the uttermost. Our feet are stable because we are now one with Jesus, we are His body, His flesh, and He is saved perfectly, completely, finally, and to the uttermost. As Jesus is, so are we in this world. 

16 Lift up over all the [covering] shield of saving faith, upon which you can quench all the flaming missiles of the wicked [one].

Looking away [from all that will distract] to Jesus, Who is the Leader and the Source of our faith [giving the first incentive for our belief] and is also its Finisher [bringing it to maturity and perfection]. He, for the joy [of obtaining the prize] that was set before Him, endured the cross, despising and ignoring the shame, and is now seated at the right hand of the throne of God. Hebrews 12:2

We have faith because Jesus is the Author and Finisher or our faith. Faith is not a human ability to believe the Truth, it is our Lord’s ability to believe the Truth working through man. We will lift up the shield of faith only because Jesus empowers us to. The Head directs the body to do its will. We are more then conquerors through Christ and our darkness is as the noonday. There is no weapon that is formed that can prosper and today is the day of our salvation and now is our accepted time.
