“My Heart Is Too Hard”

No matter how hard a person may perceive their heart to be, if they turn
in faith to God, he can soften it.

“I will give you a new heart and put a new spirit in you; I will
remove from you your heart of stone and give you a heart of flesh.
And I will put my Spirit in you and move you to follow my decrees
and be careful to keep my laws. Ezekiel 36:26 -27 (NIV)

God can do what no one else can do.

They who heard it said, “Then who can be saved?” But He said, “The
things that are impossible with people are possible with God.” Luke
18:26-27(NASB)”

God has made it possible to give us a new heart. We just have to turn to
Jesus and ask him to do the work in us
