1Paul, an apostle of Jesus Christ according to the commandment of God our Savior and the Lord Jesus Christ our hope, 2to Timothy, my true child in faith: Grace, mercy, and peace from God our Father and Christ Jesus our Lord.
3As I urged you when I was going into Macedonia, stay at Ephesus that you might command certain men not to teach a different doctrine, 4and not to pay attention to myths and endless genealogies, which cause disputes rather than God’s stewardship, which is in faith. 5But the goal of this command is love from a pure heart, a good conscience, and sincere faith, 6from which things some, having missed the mark, have turned away to vain talking, 7desiring to be teachers of the law, though they understand neither what they say nor about what they strongly affirm.
8But we know that the law is good if a person uses it lawfully, 9as knowing this, that law is not made for a righteous person, but for the lawless and insubordinate, for the ungodly and sinners, for the unholy and profane, for murderers of fathers and murderers of mothers, for manslayers, 10for the sexually immoral, for homosexuals, for slave-traders, for liars, for perjurers, and for any other thing contrary to the sound doctrine, 11according to the Good News of the glory of the blessed God, which was committed to my trust.
12I thank him who enabled me, Christ Jesus our Lord, because he counted me faithful, appointing me to service, 13although I used to be a blasphemer, a persecutor, and insolent. However, I obtained mercy because I did it ignorantly in unbelief. 14The grace of our Lord abounded exceedingly with faith and love which is in Christ Jesus. 15The saying is faithful and worthy of all acceptance, that Christ Jesus came into the world to save sinners, of whom I am chief. 16However, for this cause I obtained mercy, that in me first, Jesus Christ might display all his patience for an example of those who were going to believe in him for eternal life. 17Now to the King eternal, immortal, invisible, to God who alone is wise, be honor and glory forever and ever. Amen.
18I commit this instruction to you, my child Timothy, according to the prophecies which were given to you before, that by them you may wage the good warfare, 19holding faith and a good conscience, which some having thrust away made a shipwreck concerning the faith, 20of whom are Hymenaeus and Alexander, whom I delivered to Satan that they might be taught not to blaspheme.
The word "apostle" (apostolos, αποστολος) is from the Greek word apostello (αποστελλω), meaning to send. Paul saw himself from the time of his commission by Jesus, and confirmation in Damascus, as one who was sent by God and not by his personal desire and was equal to being one of "the twelve" that Jesus originally commissioned (other than Matthias, Acts 1:26).
To be designated as an apostle, the apostle Peter stated the standards required in Acts 1:21-25. He said in verses 21-21 that one to be an apostle required that the man must have been with the apostles from the beginning of Jesus' ministry, beginning at the baptism of John through the resurrection and ascension of Jesus to heaven. An essential addition requirement for an apostle is stated in verses 23-25, the person would be chosen with God's approval.
Paul was of a unique apostle (1 Cor 15:7-10), as the apostle to the Gentiles, and he said that one who was an apostle did the works of an apostle in 2 Cor 12:11-12.
