Power of His might. Ephesians 6:10. “Finally, my brethren, be strong in the Lord, and in the power of His might.” Older, wiser, and experienced, he passes on the word of authority from what he learned firsthand in the desert, in the cities, and in the courts of the land. From those who pretended to be the real thing; those who thought they were the real thing; from judges and priests; from rabbis and teachers, Paul learned—and then passed on to Christians in Ephesus—a fundamental charge the faith produces: “Be strong in the Lord.”
Believers in Christ need supernatural strength and courage inspired by the One who met and conquered because there are unseen dangers, and battlefields without clear boundaries. An unrelenting enemy, who is invisible, very powerful, uncontrollable, and undaunted, aims to defeat every righteous person who has placed their faith in God. We have been given instructions on how to use adaptable tactics, available strength, and power from Him, who values each of us. “Be strong in the Lord.”
Power from Him, who holds all power in heaven and earth, is freely offered to each of His own. He has supernatural power to calm storms and turn chaos into peace. He created worlds with a word and keeps order in the universe. From His lips come words to give life or take it away; His grace is revealed through those words. He offers His strength and waits for us to draw from it, for He is limitless. “The power of His might.”
Without partiality, superficiality, superfluity, hypocrisy, selfishness, purposelessness, hopelessness, or carelessness— but instead, with joy in the soul, courage in the battle, love in the heart, grace on the lips, eyes on the prize, fearlessness in the mind, and trust in the God of our salvation—we are told to “Be strong in the Lord, and in the power of His might.”
The need for divine power and the whole armor of God arises because the devil is the "accuser." Satan (adversary) is limited in his power and ability, so he has an organized system of helpers to control the people of the world in any way he can. The devil is strong, but we are told to "Resist the devil, and he will flee from you. Draw nigh to God, and He will draw night to you." Not only is the devil wily and subtle in his attacks against what should be the citadel of safety, the home, but he also engages in close combat, like wrestling.
A stand must be taken against what appeals to those without salvation in our homes, just as we must oppose attacks on us as believers. The organized world system is controlled by spiritual powers that oppose God. Demons and fallen angels are organized to make people feel discontented with what they have. Advertising is designed to make people believe they are being deprived of what they have a right to, especially targeting young people. When they are discontented at home, family life becomes endangered.
