He has made everything beautiful in its time. He has also set eternity in the human heart...

— Ecclesiastes 3:11a

I don't suggest you follow your heart, I suggest you follow God, but you do that from the heart. So you want to make sure your heart is receptive to His leading.

You do this by learning to live from your spiritual senses and desires. You see with the eyes of your heart. You receive revelation with the eyes of your heart. You can taste and see that what the Lord is giving you is good for you. You can hear His voice in your inner man/heart. You already know you can feel his presence. I think, at times, I have even smelled a sweet aroma related to His manifested presence.
