"...take up the complete armor of God, so that you may be able to withstand in the evil day, and having done all things, to stand. Stand therefore, having girded your loins with truth, and having put on the breastplate of righteousness, and having shod the feet with the readiness of the gospel of peace; besides all, having taken up the shield of faith with which you will be able to quench all the flaming arrows of the evil one. And take the helmet of salvation and the sword of the Spirit, which is the word of God..." (Ephesians 6:1 3-17)
We are instructed to "take up" God's armor of "truth", and "stand" behind the "shield of faith" in the truth of God's word. Only then can we be safe from the lier who comes to steal our security, peace, and joy in the salvation promised us by God the Father and Christ Jesus our Lord.
"The thief comes only to steal and kill and destroy. I came that they may have life and have it abundantly." (John 10:10)
"Now the spirit is saying explicitly, that in subsequent eras some will be withdrawing from the faith, giving heed to deceiving spirits and the teachings of demons in the hypocrisy of false expressions...Now profane and old womanish myths refuse...Faithful is the saying and worthy of all welcome (for for this are we toiling and being reproached), that we rely on the living God, Who is the Savior of all mankind, especially of believers. These things be charging and teaching." (1 Timothy 4:1-11)
