Furthermore, Father will guide a person's heart, following all the Wisdom that has already been provided, and even in areas that a person may not totally be able to understand or know about, themselves.  Actually, concerning all the aspects of anything, oneself may not be able to tell, because that would be to try to see the beginning or end of something...and that would be a transgression against what Father spoke of in Her Word concerning the knowledge of anything, and in man not knowing the beginning or end of Father's works.

Ecclesiastes 3:11 -- He has made everything appropriate in its time. He has also put eternity in their hearts, but man cannot discover the work God has done from beginning to end.

1 Corinthians 8:2 -- If anyone thinks he knows anything, he does not yet know it as he ought to know it.

So in the things that a person does, they can't totally determine whether or not it is right or wrong except based on Father's Spirit and all that Father has already provided.  If something does not seem to have anything wrong to it up to the senses that a person has, but Father's Spirit guides oneself from it, they should stay away from it.  If something does not seem to have anything wrong with it, and Father's Spirit guides one towards it, and everything including prayer towards Father concerning what is seeming like a course of action to take, it would definitely be good to follow Father's Spirit on those matters.  If something doesn't seem right based on what has already been provided, it must not be followed through with.  All parts will correlate.

So, for example, if there is a dessert that a person can have, and there doesn't seem to be anything wrong with the dessert, and Father's Spirit doesn't guide one's heart from it, but towards it, it's okay.  If oneself is not guided towards the dessert by Father's Spirit, they should stay from it.  If the dessert is an obvious mistake because of its obvious unhealthy contents, Father wouldn't guide oneself towards eating it, and oneself should not eat it.

Just because things seem okay within one's heart doesn't mean that things are actually okay.
