#1 in this list says it all. When things get spiritually hard or you feel like you need to push away anything that might work against God's children, pick any or all of the below and repeat as necessary. For more explaination and a set of 2-minute reading lists with scriptures for spiritual battle; see Fight Right - Scripture for Battle.

1. "For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart." - Hebrews 4:12 KJV

2. “He teacheth my hands to war, so that a bow of steel is broken by mine arms.” - Psalms 18:34 KJV 

3. “Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour: Whom resist stedfast in the faith, knowing that the same afflictions are accomplished in your brethren that are in the world.” - 1 Peter 5:8-9 KJV

4. “Hast thou not known? hast thou not heard, that the everlasting God, the Lord, the Creator of the ends of the earth, fainteth not, neither is weary? there is no searching of his understanding. He giveth power to the faint; and to them that have no might he increaseth strength. Even the youths shall faint and be weary, and the young men shall utterly fall: But they that wait upon the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.” - Isaiah 40:28-31 KJV

5. “I have set the Lord always before me: because he is at my right hand, I shall not be moved.” - Psalms 16:8 KJV

7. “In God have I put my trust: I will not be afraid what man can do unto me.” - Psalms 56:11 KJV
