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).
This world, though it consistently fails to recognize and know the Lord, should consistently recognize Christ's conversation through the life of the believer. Our conversation should always match, or become, the gospel of Christ and the new life that we have in Him. Our conversation should be holy because the Lord is holy (1 Peter 1:15). In 2 Peter 3:11, we learn that the dissolving of this world ought to cause us to walk “in all holy conversation and godliness.” In other words, our practical Christian life should resemble the change inside of us that took place at salvation. Others should see the Lord Jesus Christ in our actions and in our way of life.
