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.
God’s people have a solemn responsibility to encourage one another. Helping to build another’s godly courage remains one of the most effective ways to influence others. Unfortunately, far too many times, close acquaintances fail to encourage (and all too often discourage) one another. In these times, it is especially important that the individual learns to encourage himself in the Lord. In our passage, David returned to Ziklag only to find it burned with fire. The welfare of the women and children seemed hopeless as the Amalekites had taken them all captive. No doubt it was one of David’s most challenging times. David and his men were greatly distressed and in need of courage. Unfortunately, the men closest to David turned against him rather than supporting their leader during the most trying time. David’s only hope was to encourage “himself in the LORD his God.” Believers today need to follow David’s example. We cannot always depend upon others to receive courage, but we can always depend upon the Lord.
