That's TERRIBLE advice!!!
DO NOT LISTEN TO YOUR HEART!!!
That's terrible advice because it's simply not true.
Our hearts are sometimes right, but our hearts have been terribly wrong about some other things.
The only way we can be sure that what our hearts are telling us is right is in hindsight.
For instance, there was a time when my heart saw my wife and told me "She's the one."
And then, some time later, particularly when times are hard, that same heart told me, "Maybe she ain't the one."
And as things get even harder in marriage as it sometimes does, my heart told me, "Maybe you should look for another one!"
I can't trust something as important as my life and marriage to a heart that's inherently untrustworthy. That would be crazy to listen to my heart.
Our lives are way too important to trust something that's inherently not trustworthy.
God tells us that he has a better way - a way that's guaranteed to lead to fantastic decisions every time.
Trust in the Lord with all your heart, and do not rely on your own understanding. In all your ways acknowledge him, and he will make your paths straight. Proverbs 3.5-6
God says, don't trust your heart. Trust in the Lord with all your heart. And after we have entrusted God with our hearts, God tells us to lean not on our own understanding but to acknowledge that God is God in all our ways.
So here's how this works.
Even though my heart may tell me one thing, even though my own understanding seems to confirm what my heart is telling me, I am going to trust in God with all my heart and acknowledge that his way is better by doing life his way.
Your lives are way too important to entrust to our hearts or even to ourselves.
The best pathway in life is to trust in God with all our hearts!
