Patience Johnson said this quote
“ If you work by faith and not by sight, you will always see a sign. You have to develop a space of comfort to know that there is a difference between signs and sounds, it means God will tell you that He will make a change in your life but He won't show you anything to demonstrate the change for a little while because He doesn't want your faith to be in the change; He wants your faith to be in the promise, so that when the change is a bit slow in coming, you will know how to trust in Him while you wait for it to come to pass. ”
