For the which cause - Because I was appointed a preacher (2 Timothy 1:10-11).
I also suffer - besides my active work. Ellicott, 'I suffer even these things:' bonds, etc. (2 Timothy 1:8; 2 Timothy 1:15).
I am not ashamed - neither be thou (2 Timothy 1:8).
For. Confidence as to the future drives away shame (Bengel).
I know - though the world knows Him not (John 10:14; John 17:25).
Whom - I know what a faithful, promise-keeping God He is (2 Timothy 2:13). It is not, I know how, but WHOM, I have believed: a feeble faith may clasp a strong Saviour.
Believed - put my trust: carrying out the metaphor of a depositor leaving his pledge with one whom He trusts.
Am persuaded - (Romans 8:38).
He is able - in spite of so many foes around me.
That which I have committed unto him , [ teen paratheekeen mou ] - 'my deposit:' the body soul, and spirit (1 Thessalonians 5:23; 1 Peter 4:19). So Christ Himself in dying (Luke 23:46). God deposits with us His Word to keep (2 Timothy 1:13-14) and transmit to others (2 Timothy 2:2): God commits another deposit to us, which we should commit to His keeping-namely, ourselves and our heavenly portion. Ellicott, from 2 Timothy 1:14; 1 Timothy 6:20, 'the stewardship committed to me'-namely, of preaching the Gospel. But "keep" applies rather to Paul, the holder, than God, the Giver, of the deposit (cf. also John 17:11; 1 Peter 1:5; Jude 1:24 [ fulaxai , as here]).
Against that day - the day of His appearing (2 Timothy 1:18; 2 Timothy 4:8).
