You don’t have to know God’s will if you are confident in God’s word. God's will is not about a place, or a thing, or a time. God's will is all about the condition of your heart. That's what God really cares about. We overlook that fact when we trivialize God's will by thinking that it primarily applies between A or B or C.
Know this... God's will is more about your character than it is about making choices. God's will is more about your attitude than it is about finding answers. God's will is more about your relationship with Jesus than it is about getting results. God's will for you is about your relationship with Jesus rather than knowing. Be aware that as your LOVE for Jesus goes deeper and more driven the more you will be able to relax in a certainty that you are following God's will. And it is here, in this way of living that will help you not simply making better decisions, but more purposeful, driven, kingdom-minded initiatives.
"And so, dear brothers and sisters, I plead with you to give your bodies to God because of all he has done for you. Let them be a living and holy sacrifice—the kind he will find acceptable. This is truly the way to worship him. 2 Don’t copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think. Then you will learn to know God’s will for you, which is good and pleasing and perfect."
- Romans 12: 1-2 (NLT)
