Self-examination is not easy nor always pleasant. But Christians must do so to confirm our faith and assure our hope in Christ. The doctrine that a Christian cannot fall from God’s grace and be lost is patently false (Gal. 5:4; Heb. 2:1-3; 3:12-14; 2 Pet. 2:20-22). In today’s text, the exhortation warns of being disqualified (“unapproved, rejected,” castaway, reprobate, G96). Paul himself was not immune to the possibility of being disqualified (1 Cor. 9:27). He uses two words in today’s text to urge us to avoid being rejected by the Lord. To prevent such spiritual disaster, we must (1) Examine ourselves. We must expend effort to test and scrutinize ourselves, to explore our conduct and our heart’s motives, attitudes, and aspirations that prompt our actions. The standard we examine ourselves against is “the faith,” the gospel of Christ (Gal. 1:11, 23; Jude 3). Do the heart and behavior align with the word of Christ? (2) Test ourselves. This word means to discern whether we are approved. Vine says it means “to prove with a view to approving” (Vine, II:22). We must discern whether our assessment shows “that Jesus Christ is in” us. If it does, then good. Keep it up. If it shows we are deficient, repent and practice righteousness (2 Cor. 12:20-21; Rev. 2:5). Christians use the gospel to examine (inspect) and test (approve) ourselves. By conforming to it, we know (recognize) ourselves and are accepted by Christ.
