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 Bible clearly points out that by God’s grace the apostle Paul laid the foundation which is Jesus Christ and Him crucified. All those who have come after the apostle Paul have built upon that foundation. It is with this in mind that Paul warned believers to take heed how they built upon the foundation. The foundation has been laid, and no other foundation can be laid, but each believer must carefully examine the means by which he builds upon Christ. Not only should believers take heed to their daily walk, but self-examination is also necessary in their manner of service for the Lord Jesus Christ. Each believer should search the scriptures to ensure that his efforts glorify the Lord. Far too much effort is self-serving and selfish and not God-centric. Self-examination helps define one’s motives.
Self-examination serves as a tool for man to use to find out who and what he is. Though some preachers suggest that believers should never question their own salvation experience, the scripture encourages self-examination. If there are doubts, believers should certainly ask questions concerning the basis for their salvation. Was it based upon one’s feelings or solely upon the scriptures? They should ask what they did in order to be saved. Did they join a church, do some penitent work, or did they call upon the name of the Lord Jesus Christ by faith as dictated by the scriptures? They should ask about the effects of their salvation. Have they seen a change of heart, or are they the same that they were before trusting Christ as Saviour?
