For there is no distinction: for all have sinned and fall short of
the glory of God, and are justified by his grace as a gift,
through the redemption that is in Christ Jesus.
(Romans 3:22–24)
The first word of the gospel, as the apostle Peter proclaimed it on the Day of Pentecost two millennia ago, is repent. This single word distills the gospel message into one word:
“Let all the house of Israel therefore know for certain that God has made him both Lord and Christ, this Jesus whom you crucified.” Now when they heard this they were cut to the heart, and said to Peter and the rest of the apostles, “Brothers, what shall we do?” And Peter said to them, “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit” (Acts 2:36–38).Being wrong is not the worst thing, but willfully remaining wrong is. “And let us consider how to stir up one another to love and good works, not neglecting to meet together, as is the habit of some, but encouraging one another, and all the more as you see the Day drawing near. For if we go on sinning deliberately after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, but a fearful expectation of judgment, and a fury of fire that will consume the adversaries (Hebrews 10:24–27).
There’s much involved with repentance: “As it is, I rejoice, not because you were grieved, but because you were grieved into repenting. For you felt a godly grief, so that you suffered no loss through us. For godly grief produces a repentance that leads to salvation without regret, whereas worldly grief produces death. For see what earnestness this godly grief has produced in you, but also what eagerness to clear yourselves, what indignation, what fear, what longing, what zeal, what punishment! At every point you have proved yourselves innocent in the matter” (2 Corinthians 7:9–11).
Repentance is what the first century world needed, and it’s what the twenty-first century world needs. “The times of ignorance God overlooked, but now he commands all people everywhere to repent, because he has fixed a day on which he will judge the world in righteousness by a man whom he has appointed; and of this he has given assurance to all by raising him from the dead” (Acts 17:30–31).
Ignorance cannot be a proper defense against God’s perfect judgment. Paul said: “In past generations he allowed all the nations to walk in their own ways. Yet he did not leave himself without witness, for he did good by giving you rains from heaven and fruitful seasons, satisfying your hearts with food and gladness” (Acts 14:16–17). To the Christians in Rome, Paul wrote: “For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth. For what can be known about God is plain to them, because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse” (Romans 1:18–20).
Ignorance is removed with knowledge. But it’s not merely knowing God’s will that changes us (cf. 1 Corinthians 8:1) — because if we don’t use the knowledge, it’s useless to us. “Like a lame man’s legs, which hang useless, is a proverb in the mouth of fools. … Like a dog that returns to his vomit is a fool who repeats his folly” (Proverbs 26:7, 11). The Lord of glory spoke of two different kinds of people: those who hear and do, and those who hear but refuse to change (Luke 6:46–49). James reminds us all: “Therefore put away all filthiness and rampant wickedness and receive with meekness the implanted word, which is able to save your souls. But be doers of the word, and not hearers only, deceiving yourselves” (James 1:21–22).
We could summarize the point by contrasting King Saul and King David, likewise the apostles Judas and Peter. Saul and Judas did not repent (again, consider 2 Corinthians 7:10–11). But David and Peter were of the sort who, when they were confronted with their sin, admitted it and sought God’s forgiveness immediately. The point is not that David and Peter were perfect keepers of God’s laws, but again, they repented.
Jesus said, “unless you repent, you will all likewise perish” (Luke 13:1–5; see Matthew 4:17; 11:20–24; Luke 15:7, 10). Oh, that we would have a heart like David and like Peter. We’re all sinners (Romans 3:23; Galatians 3:22). The problem is when we’re content to stay in our sin (cf. 2 Peter 2:20–22; 1 Corinthians 6:9–11).
