The three pastoral letters or epistles are books of the canonical New Testament: the First Epistle to Timothy (1 Timothy) the Second Epistle to Timothy (2 Timothy) and the Epistle to Titus. They are letters from Paul the Apostle to Timothy and to Titus. They are generally discussed as a group (sometimes with the addition of the Epistle to Philemon) and are given the title pastoral because they are addressed to individuals with pastoral oversight of churches and discuss issues of Christian living, doctrine and leadership. While the title is not technically quite correct in that the Epistles do not deal with pastoral duties in the sense of the cure of souls, yet it is popularly appropriate as denoting the essentially practical nature of the subject matter as distinguished from the other Epistles attributed to Paul. The term "pastorals" was popularised in 1703 by D. N. Berdot and in 1726 by Paul Anton.

1 Timothy 1:9,10 For Lawbreakers

1 Timothy 1:9, 10  We also know that the law is made not for the righteous but for lawbreakers and rebels, the ungodly and sinful, the unholy and irreligious, for those who kill their fathers or mothers, for murderers, for the sexually immoral, for those practising homosexuality, for slave traders and liars and perjurers - and for whatever else is contrary to the sound doctrine
Paul says that the law is not for righteous people. At first blush this may sound a little odd but Paul's point is that God's law shows you where you have gone wrong before God not how to get right with him. It is more like a proprietary plaque revealer than like a toothpaste. There are products that will stain the plaque on your teeth so that you can see it more clearly. You then have to set about the cleaning process. The law is a little like that product in that one of its main uses is to reveal the sin in your life. It is ideal for lawbreakers and rebels then, the ungodly and sinful, the unholy and irreligious as the first table would have in mind, and, as for the second table, those who kill their fathers or mothers, (number 5) for murderers, (number 6) for the sexually immoral, for those practising homosexuality, (number 7) for slave traders (number 8) and liars and perjurers (number 9) and indeed for whatever else is contrary to the sound doctrine, one of the great concerns of these letters (see 2 Timothy 4:3, Titus 1:9). The Law then can show us where we are going wrong, where we are unsound. That is the way to use it - not as a means of becoming righteous but in order to reveal sin in your life and in your heart. A faithful preacher will preach the law in such a way that he exposes to his hearers the fact of their sin.
