He who trusts in his own heart is a fool, But he who walks wisely will be delivered.~Proverbs 28:26

“The heart is more deceitful than all else And is desperately sick; Who can understand it? “I, the LORD, search the heart, I test the mind, Even to give to each man according to his ways, According to the results of his deeds.~Jeremiah 17:9,10

For this people’s heart has become calloused; they hardly hear with their ears, and they have closed their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts and turn, and I would heal them.’~Matthew 13:5
