Paul and Barnabas admonished the heathen to turn from “vanities unto the living God.” One cannot trust in the Lord and simultaneously trust in anything else. In order for an individual to be saved, he must repent of trusting in anything other than the Lord. One aspect of repentance involves ceasing to trust vanity and turning one’s faith toward the living and true God. This saving faith needs to become a living faith following salvation. Believers should consistently turn from “vain thoughts” and love the law of God (Psalm 119:113). They should turn from the vain labours that spend their strength for nought (Isaiah 49:4) and be “steadfast . . . in the work of the Lord” knowing that their “labour is not in vain in the Lord” (1 Corinthians 15:58). Additionally, believers should turn from “vain words” (Ephesians 5:6) and hold “forth the word of life” (Philippians 2:16).
The book of Ecclesiastes contains documentation of Solomon’s life experiment apart from God. He examined the worth of subjects involving happiness, wealth, labour, and death. Ultimately, he concluded that life “under the sun” (Ecclesiastes 1:14) was vanity. The word vanity means empty or meaningless. Though Solomon wrote extensively concerning vanity, he was not the only person in the Bible to declare the vanity of life. In fact, Solomon’s father David declared that “every man at his best state is altogether vanity” (Psalm 39:5). King David added that if both men of high and low degree were laid in a balance together, they would be “lighter than vanity” (Psalm 62:9). Thus, regardless of worldly accomplishments and accolades, a life void of God remains meaningless.
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.
