But hath in due times - At the proper time; the time which he had intended; the best time: see the notes at 1 Timothy 2:6; compare the notes at Matthew 2:2.
Manifested his word through preaching - See the notes at 2 Timothy 2:10. The meaning here is, that he has made known his eternal purpose through the preaching of the gospel; compare the notes at Romans 10:14-15.
Which is committed unto me - Not exclusively, but in common with others; see the notes at 2 Timothy 1:11.
According to the commandment of God our Saviour - Paul always claimed to be divinely commissioned, and affirmed that he was engaged in the work of preaching by the authority of God; see Gal 1:1-12; 1 Corinthians 1:1; Romans 1:1-4.
