An excerpt from “What Christians Want To Know.com” entitled, “What Does It Mean To Have A Hardened Heart?” by Daryl Evans states: “Sin is ultimately the cause of a hard heart. Sin often leads to pride which leads to individuals that are more interested in trusting in their own self than in putting our trust in God.” The article may be viewed at: https://www.whatchristianswanttoknow.com/what-does-it-mean-to-have-a-hardened-heart [Reflection is based on the Bible Reference – Ephesians 4:18]
Application:
“The cure—man needs a new heart—a heart transplant if you will. The problem is that man can’t change his own heart—only God can do that. How does God do this? He does it when you put your trust in His Son, Jesus Christ. Without putting your faith in Jesus there is no hope of ever having eternal life—and you will die in your sins. The New Testament tells us that we can never earn our salvation—it is a gift that God is offering to us by His grace, received by us through our faith.” [Source: https://www.ccelkgrove.org/gods-cure-for-spiritual-heart-disease ]
