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 Lord redeemed Israel out of Egypt for the purpose of worshipping Him. Instead of willingly serving Him, the nation of Israel turned to vanities. In doing so, they ignited the fire of God’s anger (Deuteronomy 32:21-22). Ultimately, God chose to provoke Israel to jealousy with a people “which are not a people” – the Gentiles. Since Israel had provoked the Lord to anger with their vanities, He was going to use Gentiles, whom Israel knew to be “not a people,” to provoke Israel to anger. The Lord expects the redeemed to flee vanity and give themselves wholly to His work, worship, and will. The Lord has now redeemed Jew and Gentile “for his name” (Acts 15:14), and He expects the same from each of us.
The apostle Paul, through the leading of the Holy Ghost, made his way through Paphos preaching God's word. While in that country, Paul faced great resistance especially from the likes of a false prophet named Bar-jesus. Yet, in the midst of this chaos, the Bible mentions a prudent man named Sergius Paulus, the deputy of the country. He desired to hear the message preached by God's man. Sergius Paulus wanted to hear the truth because a prudent man desires to hear it no matter the opposition and the attempts to silence the words of God. Unfortunately, there seem to be many more people like the false prophet today. They want little or nothing to do with the word of God. Yet, a prudent man, whether he agrees or disagrees with what he hears, will desire to hear the words of God. He then ponders those words as he makes his decisions concerning his daily life and eternal destination.
