As it is with all sin, rebellion originates within the heart. Long before it manifests itself in the individual’s actions, it finds life by taking root within his heart. The Lord described a rebellious generation by saying that they were “a generation that set not their heart aright, and whose spirit was not stedfast with God.” A man with a wicked heart and the wrong spirit cannot enjoy sweet fellowship with the Lord. As rebellion takes root in his heart, the rebellion pushes out the desires for prayer and for God’s word. Humility is crowded out because of pride and self-will to the extent that a man justifies, perhaps even with scripture, his rebellious spirit. His once soft heart becomes hardened because of the deceitfulness of sin.
On the surface, one might superficially define peace as an absence of war, troubles, or trials. Yet, the Bible indicates a much broader concept. Two words in our passage suggest as much. The Bible says, “the work of righteousness shall be peace; and the effect of righteousness quietness and assurance for ever.” The next verse states that God’s “people shall dwell in a peaceable habitation, and in sure dwellings, and in quiet resting places.” Both verses incorporate the words quietness and assurance revealing that peace offers a quiet assurance. Fortunately, this means that peace for the child of God is not contingent upon the circumstances of life. Christians can experience peace even while enduring the worst of circumstances.
