A tender heart quickly and readily yields when offered correction; however, as a heart becomes hardened, the times of yielding become fewer and farther apart. During the hardening process, the individual finds the true nature of the heart more difficult to grasp. As the heart further hardens, the individual finds himself involved in further defiance. The mischief may start as seemingly insignificant, but a hardening heart will ultimately lead to greater depths of wickedness, some seemingly unimaginable only a short time ago. Some of the worst sins committed in the Bible by God's people were committed by those who shortly before had displayed a tender heart. Yet, they allowed their hearts to be hardened by the deceitfulness of sin.
Fear and discouragement are effective weapons in Satan’s arsenal which he uses to discourage the people of God from fulfilling the will of God for their lives. Fear is not all bad. The fear of God is good and holy, but the fear of the world withstands faith and brings the believer into bondage (Proverbs 29:25). Fear and faith are foes as are fear and courage. In 2 Timothy 1:6-8, the Bible points out that the Lord is not the instigator of fear in the life of the believer. In the place of fear, God gives men power, love, and a sound mind. God wants men to be courageous and full of faith. Yet, the fear of man exhibits a lack of courage. It frequently hinders believers from doing the Lord’s work and gives the impression that believers are ashamed of the Lord and His people.
