“For this people’s heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should heal them,” Jesus says in Matt 13:15 (KJV).

“And I will give them one heart, and I will put a new spirit within you; and I will take the stony heart out of their flesh, and will give them an heart of flesh: that they may walk in My statutes, and keep mine ordinances, and do them: and they shall be My people, and I will be their God.  But as for them whose heart walketh after the heart of their detestable things and their abominations, I will recompense their way upon their own heads, saith the Lord God.” Ezekiel 11:19-21 (KJV).

I also came across this excellent post:

“The heart of many will grow cold” – or has it already begun? Matthew 24. HWC- the global current sweeping through the world (Heart Waxing Cold)

Father, You alone see what’s really in our hearts, thou we try to hide the truth from others, You look into our hearts.  Which is why You chose David over his older brothers to lead the kingdom of Israel (1 Samuel 16:7). Help us to repent of our sins, and seek Your abundant forgiveness and kindness. In Jesus’ Name, Amen.
