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.
A zealous person is contagious, both positively and negatively. The apostle Paul cautioned that the early believers had been zealously affected, but not in a good way. Those who opposed the gospel were adamant, yet they unwisely waged war against the truth. Night and day, they zealously fought in order to hinder the ministry of the believers. Ultimately, their zeal affected the people of God. These believers who started strong were hindered by the enemies' efforts to the point that it affected their race for the Lord (Galatians 5:7). Modern day enemies of the gospel are aware of this potential pitfall for the believers. They often display more zeal than those who knowingly possess the truth. Yet, today's passage also teaches that “it is good to be zealously affected always in a good thing.” Zeal breeds zeal. Zeal in righteousness will yield righteous results.
