King Solomon said, "Keep thy heart with all diligence; for out of it are the issues of life." Proverbs 4:23
Yes out of the heart are issues, some maybe important but the majority of cases "issues" are problematic for life.
Any case or matter passing through the heart will spew out one day, in fact what's said in the heart has the most preeminence in life. The heart discharges with no hindrance whatever is in it; good or bad; personal problems, concerns, unanswered questions, difficulties and whatever imagination - it will certainly come out. It'll come out, and would not matter it's in a form of exotic smells, toxic waste, affair, business, subject, topic, question, point, point at issue, etc. Whether it's an item, thing, case, concern, theme or plight - it will come out.
Some issues of the heart are venomous, they're to rig out, scheme and obstruct others from progress. It would not matter how close you are, some hearts are bent to putting barriers and stumbling blocks on others.
Proverbs 23:26 says, "My son, give me thine heart..." And the reason God wants you to surrender him your heart is so that he may fill it with what's good so that out of the good treasure of your heart would come out that which is good, the tongue will be bridled to say only what's good, not "... the evil treasure of his heart ..... for of the abundance of the heart his mouth speaketh."
If you're a good man, out of your good treasure that you produce people will be able to pick good fruit, not rotten fruit but only good fruit- from out of the abundance of your heart that your mouth speaks.
