God directs you through your heart. That is a metaphor for your inner man. It includes your mind, conscience, will, and emotions. While many people seek outward signs from God, always consider your heart.
Effective prayer comes from your heart. God already knows your heart, but he wants you to share your heart with him through prayer. Ask him to give you understanding about what he has put in your heart. Trust him to give you a heart after his own will.
Knowing the will of God comes through his word and his providence in our circumstances, yet we do his will from the heart. If you have a desire to do his will, it is evidence that he is certainly working in your heart.
God directs you when you know it and when you don't. He works in your heart when you understand and when you can't. Say to him, "Here's my heart LORD. Work in it to bring glory to your name. Give me a heart after your own will."
"The king's heart is like a stream of water
directed by the LORD;
he turns it wherever he pleases."
