When it comes to making a decision between several options, you can often readily eliminate any options that go contrary to scripture.
When more than one option is left and you are not sure which way to go, that is when you pray a prayer of dedication and surrender of your choices to God. You ask God to reveal which road He wants you to take.
At that point the solution will either:
1. Become really obvious which choice to take. Somehow God will communicate which road to take, usually by opening doors and making the way before you.
-or-
2. If you don’t hear anything specific, then as long as you routinely delight yourself in the Lord, you can follow the desire in your heart.
