God has not left us naked before the enemy.
Finally, my brethren, be strong in the Lord and in the power of His might. Put on the whole armor of God, that you may be able to stand against the wiles of the devil. For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places. Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand. Stand therefore, having girded your waist with truth, having put on the breastplate of righteousness, and having shod your feet with the preparation of the gospel of peace; above all, taking the shield of faith with which you will be able to quench all the fiery darts of the wicked one. And take the helmet of salvation, and the sword of the Spirit, which is the word of God (Ephesians 6:10-17).
The Lord has provided us with spiritual weaponry that has the ability to counterattack and defeat any scheme that the devil would try to use against us. God knows that in order for us to successfully fight the unseen powers that have been marshaled against us, we must have His special supernatural power that He has provided for this fight. We see in Ephesians 6:10-18, Paul deals with key elements of spiritual warfare that we need to know and appropriate in our personal lives.
When you have donned the full armor of God, you have every reason to stand up straight and be confident in God!
