Ch. 1 – The Law and the Gospel coexist, each for a purpose: The Law to judge the sinner; the Gospel to save the sinner (verses 9-11; see also Galatians 3:19).
Ch. 2 – The Savior desires all men to be saved and to come to the knowledge of the Truth. ALL people (v. 4).
Ch. 3 – Verse 16 reveals the great mystery of Godliness:
– God was manifested in the flesh
– Justified by the Spirit
– Seen by angels
– Preached among the Gentiles*
– Believed on in the world
– Received up in glory
* The mystery of the Gospel is: That Gentiles should be fellow heirs of the same body, and partakers of His promises in Christ through the Gospel. (Ephesians 3:6)
Ch. 4 – What is exhortation (v. 13)?
Verses 13-16 suggest a mentor’s advice to his mentee: Devote yourself to reading, to exhortation, to teaching. Don’t neglect your giftedness. Meditate on these things. Take heed to yourself (or, keep a close watch on yourself).
Ch. 5 – Men, consider young men and boys your brothers or sons in the faith. Boys and young men, consider older guys your fathers in the faith and don’t talk back to them (v. 1).
On ministry to widows: Let the family take care of them (and learn to do so) so that the church is not burdened and can give attention to those widows who have no one else to help them (v. 16).
Ch. 6 – Paul encourages a genteel nature as a Christian man but not a character of weakness. He should fight the good fight of faith. Be a Christian gentleman, but be tough and fierce when necessary (verses 11-12).
Paul concludes his letter to his son in the faith, Timothy, on the same note that he started the letter: Whatever is contrary to sound doctrine always leads to spiritual ruin (1:3-7 and 6:20-21).
