Examine yourselves as to whether you are in the faith. Test yourselves. Do you not know yourselves, that Jesus Christ is in you?—unless indeed you are disqualified. (2 Corinthians 13:5, NKJV)
The possibility of Christians becoming disqualified and lost (severed from Christ, fallen from grace, Gal. 5:4) is both implied and explicitly stated here. To be “disqualified” means to be “unapproved, i.e., rejected” (Strong’s Dictionary). Conversely, the one who is accepted is “in the faith,” that is, “Jesus Christ is in you.” To know which is true of us, Christians should do three things. 1) Examine ourselves. Like an assayer tests “a metal or ore to determine its ingredients and quality” (Merriam-Webster), we must “endeavor to discover the nature or character” (BDAG) of ourselves. Am I “in the faith” (in harmony with the gospel, Eph. 4:1), or am I deceiving myself (Gal. 6:3; Jas. 1:22-26)? 2) Test ourselves. This word means to “try, prove, put to the test,” “to make a critical examination of something to determine genuineness” (Thayer, BDAG). We must test all things, then hold fast to what is good, and reject evil (1 Thess. 5:21-22). This includes a close, careful examination of our own work and responsibilities (Gal. 6:4-5). 3) Know ourselves. This requires humility (1 Cor. 8:2). The Scriptures help us know ourselves the way God knows us (Heb. 4:12-13). God’s word corrects us so we may live in the faith, have Christ in us, and be approved before God (2 Tim. 3:16-17; 2:15; Eph. 3:17).
30 For this reason many are weak and sick among you, and many sleep. 31 For if we would judge ourselves, we would not be judged. 32 But when we are judged, we are chastened by the Lord, that we may not be condemned with the world. (1 Corinthians 11:30–32, NKJV)
The spiritual condition of many of the Corinthian Christians was in jeopardy. The terms “weak,” “sick,” and “sleep” have spiritual (not physical) significance. These were without spiritual strength, some were spiritually ill, and some were already dead. (See John 11:11-13, where Jesus used “sleep” to mean Lazarus was dead.) We must judge our eating of the Lord’s supper in order to avoid such spiritual demise (which, by the way, shows Christians can indeed sin and be lost). This context shows we must judge our heart and our conduct in the Lord’s supper by using the Lord’s instructions about the supper (1 Cor. 11:23-26, 27-29). Such personal examination helps us avoid divine judgment, as well as condemnation with the world (v. 31, 32). Paul’s rebuke of their sin in this matter was the Lord’s discipline, to correct their error and preserve their souls. Eating the Lord’s supper is not a mindless ceremony. It is not a liturgical sacrament by which the mere partaking of it God grants sanctifying grace to the worshiper. It is a moment of solemn, proclamation and reverential remembrance of the body and blood of Jesus Christ. Christians who turn it into anything else expose themselves to condemnation, not glory.
Take heed to yourself and to the doctrine. Continue in them, for in doing this you will save both yourself and those who hear you. (1 Timothy 4:16, NKJV)
It is much easier to watch others and form opinions about them, than it is to carefully look at ourselves for our own spiritual deficiencies. And so, Paul warned the evangelist Timothy of this temptation. Self-inspection is required if we are to improve our personal faith and character. Just as building inspectors use a building code to test the integrity of buildings, self-examination must be made using a standard by which we test our attitudes and actions. The only reliable standard to use is the doctrine of Christ; the doctrine preached by Christ’s apostles and available in the Scriptures. Timothy was to teach this doctrine, and use it to examine himself. Careful attention to ourselves is not complete unless we actually do the things we have been taught. So, look at yourself through the lens of God’s word and then, do His will. Your salvation is secured as you do this. And, you will be helping save others, too.
Every way of a man is right in his own eyes, but the Lord weighs the hearts. (Proverbs 21:2, NKJV)
The ability to see ourselves as God sees us is not an easy task. The work of examining ourselves requires humility, meekness and thoroughness (2 Cor. 13:5). The word of God is the only tool available to us that equips us to successfully do so. More accurate than a surgeon’s laser, God’s word can cut to the deepest recesses of our heart to expose our sin and to compel our correction through repentance (Heb. 4:12-13). The deception that “we are always right” invariably prevents successful examination and correction of ourselves. God, who knows our hearts, has determined that we be “conformed to the image of His Son” (Rom. 8:29). Choose to let His gospel shape your heart and your conduct into the image of Christ.
