1 Timothy 1:10 is Paul’s list of behaviors that stand against sound teaching, and his point is that the law is meant to expose what is contrary to God’s good design, not to shelter the people who already live faithfully. The verse is written by the apostle Paul to his younger co-worker Timothy, whom Paul had left in Ephesus to correct false teachers in the church there.
For the sexually immoral, for homosexuals, for slave-traders, for liars, for perjurers, and for any other thing contrary to the sound doctrine…

What 1 Timothy 1:10 Means
Paul is continuing a sentence about the purpose of the law. He says that the law is good when it is used correctly, and that it is not aimed at the righteous person. Instead it speaks to a long list of wrongdoing, and verse 10 is the second half of that list, moving from sexual sins and the trafficking of people through to lying and false testimony in court. The phrase “contrary to the sound doctrine” serves as the summary: each item on the list is a way of living that clashes with the healthy, true teaching about God and how people should live.
The verse does not present a complete catalogue of sin, and it does not list every category of person God loves or every sin a believer might struggle with. It gives a representative set of examples that a first-century reader in Ephesus would have recognized. Nor does the verse promise anything directly to the reader. It describes what the law confronts, and it leaves the reader to examine their own life against the standard of sound teaching.
The Context of 1 Timothy 1:10
First Timothy is a pastoral letter, traditionally attributed to Paul and written to a church leader who was dealing with teachers who wanted to be experts in the Jewish law without understanding it. Paul opens the chapter warning Timothy about people who speak confidently about the law but do not grasp what it is for. Verses 8 and 9 are the hinge: the law is good, but its job is to restrain and reveal wrongdoing, and so it is directed toward the lawless and disobedient rather than toward those who are trying to live rightly.
Read this way, verse 10 is not a random set of insults. It is part of Paul’s argument that the law functions as a standard that shows sin for what it is. Just after the verse, in verse 11, Paul connects this to the gospel, “the Good News of the glory of the blessed God,” which he has been entrusted to proclaim. The list and the gospel belong together in his thinking: the law exposes the problem, and grace answers it.
Key Phrases in 1 Timothy 1:10
Romans 3:23
For all have sinned, and fall short of the glory of God…
(WEB)
Paul writes in Romans that all people have fallen short of God’s glory. This sits alongside 1 Timothy 1:10 by showing that the law’s exposure of sin applies to everyone, which is why the gospel is good news for all.
1 Timothy 1:15
The saying is faithful and worthy of all acceptance, that Christ Jesus came into the world to save sinners; of whom I am chief.
(WEB)
Just a few verses later, Paul says that Christ Jesus came into the world to save sinners, and he counts himself first among them. This connects the warning of the list with the mercy that answers it.
A Short Prayer From 1 Timothy 1:10
Lord, you have given us a law that is good and that shows us where we have wandered from your truth. Give us honest hearts to see what in our lives is contrary to sound teaching, especially the habits we have excused or hidden. Help us to be people who deal fairly, speak truthfully, and honor the dignity of every person you have made. When we fall short, lead us back to you with repentance, and remind us that your grace is greater than our failures. Keep our thinking clear and our conduct steady in the truth. Amen.
