Though the means of worldly safety have changed throughout time, people have always put their trust in various things to offer temporary safety. The Bible depicts those who trusted in fenced walls (Deuteronomy 28:52), nations (Isaiah 30:2-3), horses, horsemen and chariots (Isaiah 31:1), weapons (Psalm 44:6), and mountains (Amos 6:1). People today place their trust in weapons, security systems, governments, insurance policies, and even medicines. Though the sources of trust have changed, the Lord remains just as grieved today when men place their trust upon the things of this world rather than upon Him. Ultimately, every source of worldly safety will fail, often in the moment we perceive as our greatest time of need.
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.
