Stand firm therefore, having girded your loins with truth (Eph. 6:14a).
Here is what keeps our armor in place—the truth. What is the truth? Jesus said to His Father, “Thy word is truth” (John 17:17). We cannot successfully stand firm against Satan unless we know the truth with which we can counter his lies. Jesus beautifully demonstrated this during His temptation in the wilderness as He responded to Satan’s every suggestion with, “It is written.”
Paul continued:
And having put on the breastplate of righteousness (Eph. 6:14b).
As Christians, we should be familiar with two kinds of righteousness. First, we have been given, as a gift, the righteousness of Christ (see 2 Cor. 5:21). His righteous standing has been imputed to those who believe in Jesus, who bore their sins on the cross. That righteous standing has delivered us from Satan’s dominion.
Second, we should be living righteously, obeying Jesus’ commands, and that is probably what Paul had in mind regarding the breastplate of righteousness. By obedience to Christ, we give no place to the devil (see Eph. 4:26-27).
