1 Timothy 6:15-16: The Character of God
I charge you in the presence of God, who gives life to all things, and of Christ Jesus, who in his testimony before Pontius Pilate made the good confession, to keep the commandment unstained and free from reproach until the appearing of our Lord Jesus Christ, which he will display at the proper time--he who is the blessed and only Sovereign, the King of kings and Lord of lords, who alone has immortality, who dwells in unapproachable light, whom no one has ever seen or can see. To him be honor and eternal dominion. Amen.
1 Timothy 6:13-16
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.
 In Revelation 19 He is King of kings and Lord of lords. Here He who is so manifests Him. So in Daniel 7. The Son of man is brought to the Ancient of days, but in the same Chapter the Ancient of days comes.
