That thou keep this commandment - Referring particularly to the solemn injunction which he had just given him, to "fight the good fight of faith," but perhaps also including all that he had enjoined on him.

Without spot - It seems harsh, and is unusual, to apply the epithet, "without spot" - ἄσπιλος aspilos - to a command or doctrine, and the passage may be so construed that this may be understood as referring to Timothy himself - "That thou keep the commandment so that thou mayest be without spot and unrebukable." See Bloomfield, Crit. Dig., in loc. The word here rendered "without spot," occurs in the New Testament only here and in James 1:27; 1 Peter 1:19; 2 Peter 3:14. It means without any "stain" or "blemish; pure." If applied here to Timothy, it means that he should so keep the command that there would be no stain on his moral character; if to the doctrine, that that should be kept pure.

Unrebukable - So that there be no occasion for reproach or reproof; see notes on Philippians 2:15.

Until the appearing of our Lord Jesus Christ - see notes on 1 Thessalonians 2:19; 1 Thessalonians 4:16; 1 Thessalonians 5:23.

A Plain Description of the Essence and Attributes of God, Out of the Holy Scripture, So Far as Every Christian must Competently Know, and Necessarily Believe, that Will be Saves.
Although no creature can define what God is, because he is incomprehensible (Psal. cxliii. 3) and dwelling in inaccessible light (1 Tim. vi. 16); yet it has pleased his majesty to reveal himself to us in his word, so far as our weak capacity can best conceive him. Thus: God is that one spiritual and infinitely perfect essence, whose being is of himself eternally (Deut. i. 4; iv. 35; xxxii. 39; vi. 4; Isa. xlv. 5-8; 1 Cor. viii. 4; Eph. iv. 5, 6; 1 Tim. ii. 5; John iv. 24; 2 Cor. iii. 17; 1 Kings …

Conflict and Comfort.
"For I would that ye knew what great conflict I have for you, and for them at Laodicea, and for as many as have not seen my face in the flesh; that their hearts may be comforted, being knit together in love, and unto all riches of the full assurance of understanding, to the acknowledgment of the mystery of God, and of the Father, and of Christ."--COL. ii. 1, 2. Although he was in prison the Apostle was constantly at work for his Master, and not least of all at the work of prayer. If ever the words …

"But Seek Ye First the Kingdom of God," &C.
Matt. vi. 33.--"But seek ye first the kingdom of God," &c. O "seekest thou great things for thyself," says God to Baruch, (Jer. xlv. 5) "seek them not." How then doth he command us in the text to seek a kingdom? Is not this a great thing? Certainly it is greater than those great things he would not have Baruch to seek after, and yet he charges us to seek after it. In every kind of creatures there is some difference, some greater, some lesser, some higher, some lower; so there are some men far above …
