Stand therefore, having fastened on the belt of
truth, and having put on the breastplate of righteousness, and, as shoes for
your feet, having put on the readiness given by the gospel of peace. In all
circumstances take up the shield of faith, with which you can extinguish all
the flaming darts of the evil one; and take the helmet of salvation, and the
sword of the Spirit, which is the word of God, praying at all times in the
Spirit, with all prayer and supplication. To that end, keep alert with all perseverance,
making supplication for all the saints, and also for me, that words may be
given to me in opening my mouth boldly to proclaim the mystery of the gospel,
for which I am an ambassador in chains, that I may declare it boldly, as I
ought to speak.
(Ephesians 6:14–20 ESV).
Having covered each component of the armor of God, we understand that we cannot succeed against the Devil if we rely on ourselves. We need the belt of truth to keep the daggers of false doctrine from cutting our legs out from under us. Christ’s imputed righteousness gives us ultimate protection from condemnation and accusation, and the breastplate of a Spirit-developed righteous character guards against the powerful blows of sin that try to destroy our hearts. The shoes of the gospel of peace give us solid footing and ready us to fight. Faith acts as a shield that drives us to seek shelter in God against the flaming arrows of enticing temptations. And today we come to the Helmet of Salvation. This part of our battle equipment protects our minds, enabling us to remain focused on the kingdom. We will see tomorrow that the Scripture is our mighty sword, the weapon that brings the Lord’s enemies to submissive repentance and keeps us on the narrow way by forcing us to our knees in gratitude for salvation and sorrow for sin.
Our ultimate reliance on Christ for
success in spiritual warfare is underscored in today’s passage. The participial
phrase used in this verse, “praying at all times in the Spirit” (v. 18), covers
everything that comes before it. In so doing, it indicates that we put on the
armor of God by consistent, persistent prayer. Praying “at all times” is
nothing less than taking every opportunity to be in a relationship with the
Lord that acknowledges our weakness and our need for the Lord’s power against all
of those principalities and powers that seek our destruction. Prayerful
dependence must be the consistent attitude of our hearts, both in difficult
times that make us quick to run to God and when prosperous seasons tempt us to
forget our need for Him. John Calvin writes, “Paul therefore desires us to
allow no opportunity to pass — on no occasion to neglect prayer; so that
praying always is the same thing as praying both in prosperity and in
adversity.”
Prayer is to be made in the Spirit (v.
18), which is not a reference to speaking in tongues. Instead, it refers to
petitioning God for specific things (“all prayer and supplication”) through the
Spirit, who is the One who prompts us to pray and then takes what we offer and
makes it acceptable to the Father (cf. Romans 8:26). The Lord wants us to make
specific requests, understanding that they will be granted in accordance with
His perfect will (cf. James 4:2; 1 John 5:14).
In addition to being specific in prayer,
God also wants us to be persistent in intercession (v. 18). This is a good
reminder for us today, as we are likely to give up praying when we feel as if
we have not received an answer in a timely manner. But we must persevere in
asking for God’s help, even if it seems He is delaying His response. It is the
acknowledgement that God’s timing cannot always be understood, though it can
always be trusted!
