I try to be careful because the Bible says that "the heart is deceitful above all things." In some cases, yes, I believe God puts something in us that helps guide and protect us. But many times we want what we want... and it's not what God wants. This seems to be particularly true in terms of "love" and relationships--we often want something, or push something, that is truly and honestly not from God, and it gets us into trouble. I'm guilty of this several times over.
The advice is to always "listen to your heart", but it's been well-said that the heart wants what it wants. Your heart is going to want that cute celebrity lookalike who flirts with seemingly just you and most people will throw all sensibility out the window while entertaining such an idea.
Rather, the Bible tells us there is safety in many counselors. I might think something looks good for my life... but what do my parents, mentors, and pastors say? Generally, if "my heart" is saying X and they're all saying Y... My "intuition" is most likely just my own will leading me off into la-la land.
And I wind up paying for it dearly.
