From Bobbie Houston:
Capacity is drawn from God's promise. When you know God's promises, you find strength and enablement.
Capacity is drawn from the Truth. In knowing God's truths, your capacity is increased.
Capacity is drawn from the Cause. Capacity to continue is increased as long as you remember the reason for your pursuits.
Gods Words are life-giving thoughts
The devil likes to muddy our thinking and our calling.
Never make a decision in a place of confusion.
God is not a God of confusion. So clear your mind when you feel confused. Romans 12.
Fear is not of God.
Be content with your weakness as this allows a showcase of Gods strength over you (2 Cor. 12:9) - morpheo.
