It is undeniable that the Bible speaks clearly about the issue of repentance. Other than a correct understanding of what that is or what it means, the burning question in many people’s hearts is a simple, “Why should I repent?” Consequently the answer to this question comes easily when someone understands the full message of the gospel.
Before I even get into this discussion, I must try to articulate the friction that is present when Christians talk about repentance. If you put the wrong emphasis on it, repentance then becomes a means of salvation by works which is unbiblical. If you put no emphasis on repentance with the desire to avoid the incorrect emphasis we just saw, the message is that the life of a believer is no indicator of the validity of the claim of being saved (i.e. I can live like the devil because I am saved by grace). Both of these sides miss the correct understanding of what the New Testament is saying.
Repentance and faith are two responses to the grace of God in salvation that go hand in hand. I do not believe that one can truly occur without the other. To really get the point of why someone should repent, I need to paint the picture a bit first so that the actions will have their proper context.
The Bible is clear that all men, if judged by their own actions and merits, are wicked and evil in the sight of God and “even though every inclination of his heart is evil from childhood.” (Genesis 8:21) And no good deed that we do is even reckoned as a good deed in God’s eyes, “For all of us have become like one who is unclean, And all our righteous deeds are like a filthy garment; And all of us wither like a leaf, And our iniquities, like the wind, take us away.” (Isaiah 64:6). Also, not only are we unrighteous and evil, but Paul emphasizes this by quoting the Psalms when he wrote, “as it is written, "THERE IS NONE RIGHTEOUS, NOT EVEN ONE; THERE IS NONE WHO UNDERSTANDS, THERE IS NONE WHO SEEKS FOR GOD;” (Romans 3:10,11).
God sees every thought, word, and deed that we have as being wretched and, in the language of Isaiah 64:6, only as pure and clean as a used menstrual cloth. This is not even dealing with what we, as men and women, would consider less than righteous or bad things that we do. J.C. Ryle, the first Anglican Bishop of Liverpool, provided this illustration on humanities perspective on our own sinfulness:
“We, on the other hand—poor blind creatures, here today and gone tomorrow, born in sin, surrounded by sinners, living in a constant atmosphere of weakness, infirmity and imperfection—can form none but the most inadequate conceptions of the hideousness of evil. We have no line to fathom it and no measure by which to gauge it. The blind man can see no difference between a masterpiece of Titian or Raphael and the queen’s head on a village signboard. The deaf man cannot distinguish between a penny whistle and a cathedral organ. The very animals whose smell is most offensive to us have no idea that they are offensive and are not offensive to one another. Fallen men and women, I believe, can have no just idea what a vile thing sin is in the sight of that God whose handiwork is absolutely perfect—perfect whether we look through telescope or microscope;”1
Establishing the fact that all humanity is wicked, and that includes every individual from the lowest to the highest, is the first and hardest truth for anyone to see and accept. It is not much easier (if it is in fact easier at all) for a person to see and accept that our status as unrighteous sinners is so offensive a holy God that He, also being totally just and totally righteous, should punish all humanity in an eternal hell where, in the words of Jesus Himself, it is described as “unquenchable fire” (Mark 9:43) and a place “where THEIR WORM DOES NOT DIE, AND THE FIRE IS NOT QUENCHED.” (v. 48)
That was both the bad news and the truth. The good news is that Jesus Christ, God Himself, came to earth as one of us (John 1:1,14) where He lived a perfect life but He was crucified, died because of the sinfulness of mankind, and was resurrected to life again. God made Jesus Christ, the perfect and sinless God-Man, to suffer the just penalty of God’s wrath on behalf of all of those who would truly believe in Him. This was done so that these same undeserving, unrighteous, and wretched sinners would be given the righteousness that is Christ’s in order to be acceptable before God and inherit eternal life (see 2 Corinthians 5:21).
The bible makes it explicitly clear that men are saved by God’s grace alone. We are not saved, justified, or born again by any action or pious religious ceremony. Salvation must be received in this way (by grace alone) because we are like dead men in sin (Ephesians 2:1,5; Colossians 2:13), and dead men can’t do anything. In His divine providence, God has shown that our only acceptable human response to this gracious offer is to have faith (Romans 5:1; Ephesians 2:8,9; Titus 3:5) that is shown by repentance (Matthew 7:16; John 15:5,6; James 3:8-12; ). This means that our thoughts, words, and deeds are now (by the grace of God) are no longer sinful by design or apathy, but are formed with the goal of honoring God.
2 Why repent? Because no expressed faith has any validity before men or God if it is not proven by the actions of that same person (see James 2) If you live like the devil, no matter what you know in your head about God, then your actions and intentions of your heart testify to where your love and devotion truly are, and it is not with God. Furthermore, not only is repentance a biblical mandate and it must be present in a truly saved person, but it makes complete and total sense.
Imagine that you are married to a faithful and loving wife. However, you have been a cheating on her and now your brother has confronted you and has shown you how awful that is, and he has persuaded you to make it right with her. You then go up to her and say, “I’ve been cheating on you, and I’m sorry about that. Please forgive me.” She is gracious; she is more gracious than any other wife would ever be, and she says that she will forgive you and love you. However, within the next day or two you go back to the same woman that you were committing adultery with and continue that sordid affair. If this is the case, how truthful was your apology? Not truthful at all! You have shown that you are not sorrowful over the sins against your wife by your willingness to continue doing them.
It is the same way with God. If we say with our mouths that we are sinners and are in need of forgiveness and request the blood of Christ to be applied to our sins but yet we are unwilling to forsake the very things that so alienated us from God in the first place and required the death of God on the cross to pay their penalty, then we do not value the forgiveness of Christ and have shown that we did not, in fact, ever receive it.
Why repent? Because if you truly understand the penalty that you justly deserve, and you then look at the selfless and self sacrificial offering of Christ so that if you truly place your faith in him you wouldn’t have to suffer that eternal punishment, then your response is an overwhelming sense of gratitude and indebtedness. You can then say, with Paul, that you are a slave of Christ because you were bought by such a great price. Then, your only desire is to please your master who has redeemed you.
Place your faith in Christ and repent of your sins, otherwise you will incur the just punishment of a holy God forever and ever.

2 I cannot stress enough that the works are not the means or the reason why a person receives the righteousness of Christ, but it is only the result of – the fruit of – having already received forgiveness of Christ and being made new (2 Corinthians 5:17; Ephesians 4:24; Colossians 3:10)or born again (John 3:8). Being baptized, taking communion, being a pastor, a deacon, or going to church are not actions that contribute in any way to the attaining or maintaining of your salvation.
