9 For the law was not intended for people who do what is right. It is for people who are lawless and rebellious, who are ungodly and sinful, who consider nothing sacred and defile what is holy, who kill their father or mother or commit other murders. 10 The law is for people who are sexually immoral, or who practice homosexuality, or are slave traders, liars, promise breakers, or who do anything else that contradicts the wholesome teaching
Matthew Henry's Commentary on 1 Timothy 1:9-10
Commentary on 1 Timothy 1:5-11
(Read 1 Timothy 1:5-11)
Whatever tends to weaken love to God, or love to the brethren, tends to defeat the end of the commandment. The design of the gospel is answered, when sinners, through repentance towards God and faith in Jesus Christ, are brought to exercise Christian love. And as believers were righteous persons in God's appointed way, the law was not against them. But unless we are made righteous by faith in Christ, really repenting and forsaking sin, we are yet under the curse of the law, even according to the gospel of the blessed God, and are unfit to share the holy happiness of heaven.
