In John’s epistle to the elect lady and her children (2 John 1), he encouraged them to look to themselves so that he, and those with him, might not lose those things which they had wrought. In order for John to receive a full reward, those to whom he had ministered must take heed to their own service and their walk before the Lord. This line of thinking seems to be less emphasized today in many Bible-believing groups. However, it is a truth set forth by the scriptures. Paul reiterated this truth in Galatians 4:11 when he said, “I am afraid of you, lest I have bestowed upon you labour in vain.” In 1 Thessalonians 2:19, he declared that God’s people were his hope, joy, and crown of rejoicing. You might say that Paul concluded the matter when he asked, “are not ye my work in the Lord?” (1 Corinthians 9:1).
It has always been easier for man to see the problems in the lives of others. In fact, the problems we most easily identify in others are often the sins with which we personally struggle. Oftentimes, believers see these problems and immediately rush to rebuke or admonish those in error without considering their own lives first. According to Galatians 6:1, those overtaken in a fault should not be admonished until the restorer has first considered himself. The Bible says, “lest thou also be tempted.” 1 Corinthians 10:12 contains a similar principle and admonition: “Wherefore let him that thinketh he standeth take heed lest he fall.” Believers should not be easily deceived by their own conditions and must be willing to call their own standing into question first. Remember that those who have fallen should serve as a warning to every believer.
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.
