Paul, an apostle of Christ Jesus by command of God our Savior and of Christ Jesus our hope, greets Timothy, his true child in the faith, with grace, mercy and peace. He reminds him that he urged him to remain in Ephesus, when he was going to Macedonia, to charge certain persons not to teach a different doctrine or devote themselves to myths and endless genealogies, which promote speculation rather than the stewardship from God that is by faith. The aim of the charge is love that comes from a pure heart, a good conscience and a sincere faith. Some have swerved from these into vain discussion, desiring to be teachers of the law without understanding what they say.
The law is good if one uses it lawfully, understanding that it is laid down not for the just but for the lawless and disobedient; Paul lists several sins and relates them to the sound doctrine of the gospel of the glory of the blessed God, with which he was entrusted. He thanks Christ Jesus, who strengthened him and appointed him to his service, though formerly he was a blasphemer, persecutor and insolent opponent. He received mercy because he acted ignorantly in unbelief, and the grace of our Lord overflowed for him with the faith and love that are in Christ Jesus.
The saying is trustworthy and deserving of full acceptance: Christ Jesus came into the world to save sinners, of whom Paul is the foremost. For that reason he received mercy, so that in him, the foremost, Jesus Christ might display his perfect patience as an example to those who were to believe in him for eternal life. Finally Paul charges Timothy, in accordance with the prophecies made about him, to wage the good warfare, holding faith and a good conscience. Some have made shipwreck of their faith, among them Hymenaeus and Alexander, whom Paul handed over to Satan so that they may learn not to blaspheme.
