"When God gives a vision and darkness follows, wait. God will make you in accordance with the vision He has given if you will wait His time. … Abraham went through thirteen years of silence, but in those years all self-sufficiency was destroyed; there was no possibility left of relying on commonsense ways. Those years of silence were a time of discipline, not of displeasure."
— Oswald Chambers
