God does not ask you to see everything first before you trust Him. Faith often begins precisely at the point where your sight falls short. You don't have to understand every detail to be obedient. But there's also the confrontation: many people call themselves believers, yet they only move when everything feels certain. That is not faith; that is control with a pious veneer. Walking by faith means that God's Word outweighs your feelings, your circumstances, and your need for guarantees.
