Often persons think that being a member of a local assembly of Christians makes them right with God individually. If that were true, the apostle Paul would not have admonished: “Examine yourselves, to see whether you are in the faith. Test yourselves. Or do you not realize this about yourselves, that Jesus Christ is in you?—unless indeed you fail to meet the test!” (2 Corinthians 13:5, ESV). Just because we are associated with others who are following Christ does not necessarily mean that each one of us is following Christ individually.
The Bible clearly tells us to “repent and believe the gospel” (Mark 1:15). If anyone in an evangelical church is asked whether he has repented of his sins and believes the gospel, he is likely to answer in the affirmative. One cannot help but question the sincerity of a person’s repentance and belief if that person is known to sin without concern. Far too many professing Christians miss worship on Sunday because they had rather hunt or fish or even do work that is not required to be done. Church members make ungodly statements on Facebook, fail to return things borrowed, fail to acknowledge all their income when paying taxes. In these and many other ways, professing believers reveal the insincerity of their repentance.
Thomas Manton (1620-1677) gave us this warning: “If an unregenerate man should leave off sin under fear of death or hell, it would not be out of hatred to sin, but out of the fear of the punishment, as the bird is kept from the bait by the scarecrow.” Similarly, William Gurnall (1617-1679) wrote: “Take heed thou prayest not with a reservation, be sure thou renounces what thou wouldst have God remit. God will never remove the guilt as long as thou entertains the sin. . . . It is desperate folly to desire God to forgive what thou intends to commit. Thou hadst as good speak out, and ask leave to sin with impunity, for God knows the language of thy heart, and needs not thy tongue to be an interpreter. . . . Hypocrisy is too thin a veil to blind the eyes of the Almighty. Thou mayest put thy own eyes out, so as not to see Him; but thou canst never blind His eyes that He should not see thee.”
Someone may immediately protest: “You have no right to question the genuineness of my repentance and faith in Christ just because I attend worship irregularly or because I make some comments you disapprove.” The purpose here is not for any of us to examine anyone else. The purpose before us is to examine ourselves. Paul wrote: “Examine yourselves, to see whether you are in the faith.” We need to ask ourselves: “Do I truly repent of my sins? Am I really trusting in Christ? If I am, what does my life say about my profession?”
Matthew Henry (1662-1714) provides counsel as applicable today as when he penned his thoughts: “By repentance we must lament and forsake our sins, and by faith we must receive the forgiveness of them. By repentance we must give glory to our Creator whom we have offended; by faith we must give glory to our Redeemer who came to save us from our sins. Both these must go together; we must not think either that reforming our lives will save us without trusting in the righteousness and grace of Christ, or that trusting in Christ will save us without the reformation of our hearts and lives. Christ hath joined these two together, and let no man think to put them asunder. They will mutually assist and befriend each other. Repentance will quicken faith, and faith will make repentance evangelical; and the sincerity of both together must be evidenced by a diligent conscientious obedience to all God’s commandments. Thus the preaching of the gospel began, and thus it continues; still the call is, Repent, and believe, and live a life of repentance and a life of faith.”
