Hearts feel nothing. They think nothing. They beat blood, day in and day out, until you die. Don't base decisions on them. Or anything else, for that matter. Except your blood. You can base your blood on your heart, or at least your heart beat. Things of an anatomical nature can be based on your heart. Philosophically, though, and theologically, and practically, don't think with your heart. That's what you have a brain for. And a Bible. Use them, and use them wisely. Walk uprightly. Love God, serve God, love others, serve others, as God has commanded.
