1 Corinthians 1:8

Who. That is, the Lord Jesus Christ (v. 7). Confirm. Or, “establish.” Unto the end. Compare Phil 1:10; 1 Thess. 5:23; Jude 24. This statement must not be construed as teaching that it is impossible to fall away from grace. That defection for the believer is possible is clearly revealed in other scriptures (see, for example, Heb. 6:4-6). Believers will be confirmed unto the end only if they endure unto the end (Matt. 24:13; see on John 10:28). Blameless. The believers are assured that Christ will make them firm in the midst of trials and temptations and keep them in the path of holiness throughout life, so that at Christ’s coming they will be found unreprovable. It is not a promise that they would be perfect in the sense of never having made a mistake, for “all have sinned” (Rom. 3:23). Jesus will enable them to live victoriously if they submit to Him constantly, demonstrating that they seek to please Him. At His coming they will be found unreprovable because they are covered with His righteousness. “Blameless” must be distinguished from “perfect.” “Blameless” describes those who cannot be charged with any crime, who stand before the Judge unaccused, and against whom there is no ground for accusation.
