As opportunities present themselves, we ought to “do good” unto others. Scripturally speaking, we have a basic duty to help “all men,” but our foremost responsibility should be directed toward those “who are of the household of faith.” Regardless of our heart’s desire, the Lord knows there are times when we cannot help those in need. This fact should never be used as an excuse when we have a genuine opportunity, as the good that we might do to others does not always merely involve financial help. Acts chapter 3 offers an example of Peter and John who were faced with such a situation. Peter responded, “Silver and gold have I none; but such as I have give I thee” (Acts 3:6). Where these men lacked any monetary opportunity to help the lame man, they fulfilled their responsibility by imparting help in the way that God had especially enabled them.
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.
