Nahum 1:7
7 The LORD is good, a strong hold in the day of trouble; and he knoweth them that trust in him.
God knows our every thought. He knows what is truly in our hearts. That is why when we say we trust in him for our needs, he knows if that is true or not. God knows which ones he told to take the leap of faith, who would make that leap and not think twice if God was going to catch them. So, if you are struggling with having faith, don’t lie and say that you fully trust God, because he knows already knows the truth.
