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. (Ephesians 6:10-12 NKJV)
Strong Fragility... I don't now nor have I ever believed the Fragility part. I have dealt with Women Warriors, Women Law Enforcement officers, a Mother, and a very tiny wife who can become a seriously scary person when it is necessary.
