"The Lord directs our steps, so why try to understand everything along the way?" - - Proverbs 20:24
God reveals just enough of the future to increase your dependence on Him. God alone knows everything about the future, and so He wants you to be a part of His work in it, so you must rely on Him to lead you there. That is the essence of what it means to live by faith. Faith in trusting God to lead you into the future He promises you rather than trying to create your own future by yourself.
The Plan: Are you charting your own future, or are you following God into the future
