God begins every miracle with a mind photograph. This is normal. Every architect draws a picture before the building begins. Abraham visualized his generations of children every time he beheld the stars at night.
Use your memory. Replay past victories. Use your imagination to preplay in your mind those miracles that your heart has desired from the Lord. David did this and defeated the giant, Goliath.
“And he brought him forth abroad, and said, Look now toward heaven, and tell the stars, if thou be able to number them: and he said unto him, So shall thy seed be.”
(Genesis 15:5)
