Heres some verses that might explain better what im trying to say.
Jer.17:9
9The heart is deceitful above all things, and desperately wicked: who can know it?
KJV above all things , their is nothing more decietful.
Gen 6:5-6
5And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
6And it repented the LORD that he had made man on the earth, and it grieved him at his heart.
KJV
Prov 28:26
26He that trusteth in his own heart is a fool: but whoso walketh wisely, he shall be delivered.
KJV another words don't trust in your heart.
Jer 16:12
12And ye have done worse than your fathers; for, behold, ye walk every one after the imagination of his evil heart, that they may not hearken unto me:
KJV notice they don't follow God , by following what they thought was right {emotions} they didn't listen to what Gods Word said.
Mark 7:21-23
21For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders,
22Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness:
23All these evil things come from within, and defile the man.
KJV Look at the history of the children of israel they were given laws to follow , but they liked the way the egyptions served their gods so they trusted their emotions more than God, and built a golden calf to worship God , which he forbade . ex. 20:4 Thou shalt not make unto thee any graven image , or any likeness of any thing that is in heaven above , or that is in the earth beneath , or that is in the water under the earth.
I hope this helps what i'm trying to explain, sorry to hear about your wife !
