If I feel that I am defeated and have lost confidence in my ability to win, I need to sit down, take a piece of paper and make a list, not of the factors that are against me, but of those that are for me.
If anybody thinks constantly of the forces that seem to be against him or her, that person will build them up into a power far beyond that which is justified. They will assume a formidable strength which they do not actually possess.
But if, on the contrary, I mentally visualize and affirm and reaffirm my assets and keep my thoughts on them, emphasizing them to the fullest extent l rise out of any difficulty regardless of what it may be. My positive self will reemerge and, with the help of God, lift me from defeat to victory.
2 Corinthians 10:4
For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;
Philippians 4:13
I can do all things through Christ which strengtheneth me.
