I can add that to receive the guidance and guidance of our God, is to see if what we want to do in good, nice and perfect, if it is something that does not harm anyone and if it is a collective blessing. Everything good is placed in the heart of man.
Philippians 2:13
Because God is the one who produces in you both the will and the >doing, by his good will.
Sometimes we believe that we are right, and we do not seek the guidance of God, it is there where man moves away from wisdom and evil seems good. I believe as you say the good is in the heart that has allowed our Lord to dwell in it and know how to do what is "good, pleasant and perfect". Sorry for the lateness of the answer.
