The apostle then goes equally into detail with regard to servants, that is, slaves. They were to respect their masters, in order that the doctrine of the Lord should not be blasphemed. When the masters were believers, there was naturally more familiarity, for they were one in Christ, and thence the danger (for the flesh is crafty) that the servants might not treat their masters with the respect due to them. The apostle guards against this abuse of christian love, and of the just intimacy and confidence which ought to exist between brethren; but which, on the contrary, was a motive for the servant to render all honour to his master, by treating him with more love and with the same respect.
It was necessary that the apostle should be firm. All other instruction-all refusal to receive the wholesome words of christian doctrine, the words of Christ and the doctrine which is according to practical godliness-proceeded from the flesh, from human pride in those who wished to take advantage of godliness, and make it a means of gain. From such persons Timothy was to turn away. Godliness was indeed gain, if they were contented with what they had; and the Christian, who does not belong to this world, if he has food and raiment, ought to be content therewith. He brought nothing into this world, and will certainly carry nothing out of it. And the love of money is a root of all sorts of evil. Seduced by this covetousness, some had wandered away from christian faith and had pierced their hearts with sorrow. The desire to be rich was the path of snares and temptation, of foolish and hurtful lusts. Timothy was to flee these things, as a man of God. This is always the thought here: he was in the world on the part of God; he represented Him for his part in the work. He was therefore to follow after other things than earthly riches-the character of a man of God-righteousness, godliness, faith, love, patience, meekness: these were the things which, in man, presented God to the world and glorified Him.
Meanwhile there was conflict: he must fight the good fight of faith. If any one represents God in the world, there must be warfare, because the enemy is there. The energy of faith was also necessary, in order to lay hold of eternal life in the midst of the seduction and difficulties which the " things that are seen " presented. God, moreover, had called Timothy to this, and he had made a good confession before many witnesses.
Finally, the apostle charges him most solemnly in the presence of God, the Source of life for all things and of Christ Jesus who had Himself borne witness without wavering before the powers of this world, placing him under the responsibility of keeping the commandment without spot, unrebukable until the appearing of our Lord Jesus Christ.
It will be noticed here that, as Paul had not spoken in the epistle of the privileges of the assembly, but of its responsibility, so neither does he here speak of its being caught up but of its manifestation, when the fruits of faithfulness (or of failure in it) will be gathered, and every one be in his place in the visible glory according to his work. All are like Christ, all enter into His joy; but to sit at His right and left hand in His kingdom is the portion of those for whom it is prepared by His Father, who bestows it according to the work which He has granted each to perform, giving him power to accomplish it, although in grace He reckons it as our own.
Christ Himself is here viewed as the faithful man (ver. 13), whom God will manifest in glory before all creatures at the time ordained in His counsels.
All here is responsibility before the world, or glory as the result of that responsibility. The supreme, invisible God is maintained in His majesty; and He presents the Lord Jesus Christ in the creation as its centre, and repository of His glory---He who dwells in light inaccessible, whom, in His divine essence, man has not seen and cannot see.
This character of the epistle is very remarkable. Nowhere else is the inaccessible majesty of God, as God, thus presented. His character is often the subject of instruction and manifestation. Here He alone has essential immortality. He dwells in inaccessible light. He is ever invisible to the eyes of men. He alone has power. He has dominion over all who reign. It is God in the abstraction of His essence, in the proper immutability of His being, in the rights of His majesty, veiled to all men.
Now Christ will be the centre of the visible glory. Having part in the divine glory before the world was, He displays, in the human nature in which He took part, this glory, which is rendered visible in Him, causing His own to participate in His joy and in all that He has in this character; but here, He is manifested by God, and in order that all should acknowledge Him.  And it is our responsibility, faithfulness to which will be manifested in that day, which is here set before us. However small may be our share of responsibility, it is of such a God as this that we are the representatives on earth. Such is the God before whom we are to walk, and whose majesty we are to respect immediately in our conduct, and also in our relations to all that He has made.
The apostle concludes his exhortation to Timothy by engaging him to warn the rich not to rest on the uncertainty of riches, but on the living God who gives us richly all things to enjoy. It is still the supreme and Creator-God who is before our eyes. Moreover, they were to be rich in good works, and ready to give; to be rich in those dispositions which would be of value, which would lay up a store (this is but a figure) against the time to come; and to lay hold of that which really is life. The apostle repeats his urgent exhortation to Timothy to keep that which had been committed to him, to avoid profane and vain babblings, holding fast the sound and sanctifying truth, and to have nothing to do with oppositions of human science, which pretended to penetrate into divine things as though they were subject to its knowledge. This was the origin of the fall of many with regard to christian faith.
I do not doubt that, in the manner in which the apostle here sets God before us, he refers to the foolish imaginations to which, under the influence of the enemy, men were abandoning themselves. Thus he speaks of these with relation to the majesty of His Being as the one only God in whom is all fullness, and with regard to the sobriety of practical morality, which keeps the heart under the influence of that truth, and apart from the false and vain speculations in which the pride of man indulged itself. He maintained souls by the majesty of the only God in the practical sobriety in which peace dwells.
Soon will the veil be drawn aside by the appearing of Jesus, whom the Almighty God will display to the world.
