Ephesians 6:10-12 Finally, my brethren, be strong in the Lord, and in the power of his might. Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
Deuteronomy 31:6 Be strong and of good couage, fear not, nor be afraid of them: for the Lord thy God, he it is that doth do with thee; he will not fail thee, nor forsake thee.
Philippians 1:28, Joshua 1:7-9, Judges 6:11,12, and Isaiah 41:13
