1 John 5:17
All unrighteousness is sin: and there is a sin not unto death.
1 John 5:17 (KJV)
Context
This verse appears near the end of John’s first epistle, written by the apostle John, known as the disciple whom Jesus loved. He addressed false teachings and urged believers to practice genuine love and faith. In the immediate context, John has been teaching about confidence in prayer and the assurance believers have in Christ. He has just spoken of interceding for a brother or sister who sins, distinguishing between sin that leads to death and sin that does not (1 John 5:16). Verse 17 then summarizes the principle behind that distinction.
Meaning
John makes a straightforward statement: all unrighteousness is sin. Unrighteousness refers to any behavior or action that contradicts God’s righteous and moral standards as revealed in Scripture. Because God is holy and calls His people to live holy lives, anything contrary to His will is sinful. There is no gray area; every wrongdoing falls under this category.
The second part, “there is a sin not unto death,” has been interpreted in various ways. It is often understood to refer to sins that do not result in spiritual death or eternal separation from God. Some suggest it means lesser sins, while others propose it refers to sins committed out of ignorance or weakness rather than deliberate rebellion. The phrase points back to the preceding verse, where John speaks of a sin “not unto death” for which one may pray, in contrast to a “sin unto death” for which prayer is not prescribed. The point is that while all unrighteousness is sin, not every sin carries the same consequence.
This distinction should not be used to downplay the seriousness of any sin. Every sin separates us from God, and the ultimate consequence of sin is death. John also warns about the seriousness of sin elsewhere in his writings. The “sin not unto death” is a pardonable sin, one for which repentance and forgiveness are available. The sins of David and Peter illustrate this: both committed grave unrighteousness against God and man, yet they were forgiven and did not result in spiritual death.
Biblical connections
This verse connects with John’s broader teaching on Christian assurance and confidence in prayer. It encourages believers to intercede for those who sin, while acknowledging that sins differ in severity and consequence. The seriousness of sin is consistently taught throughout Scripture, and the availability of forgiveness for sins committed in weakness is a recurring theme.
Application
For believers today, this verse calls for a sober view of sin: every unrighteous act is sin and matters to God. At the same time, it offers comfort. Sins committed in weakness or ignorance are not beyond the reach of God’s grace. When we see a fellow believer stumble, we can pray for them, trusting that God is ready to forgive and restore. This should lead us to repentance in our own lives and to intercession for others, without treating any sin lightly.
Reflection
John’s words remind us that God’s holiness and His mercy are both real. All unrighteousness is sin, yet not every sin leads to spiritual death. This tension should drive us to rely on Christ’s advocacy and to walk in the light, confessing our sins and extending grace to others who fail.
