A pillar in the temple - There is probably all allusion here to the two pillars in the temple of Jerusalem, called Jachin and Boaz, stability and strength. The Church is the temple; Christ is the foundation on which it is built; and his ministers are the Pillars by which, under him, it is adorned and supported. St. Paul has the same allusions, Galatians 2:9.

I will write upon him the name of my God - That is, I will make him a priest unto myself. The priest had written on his forehead קודש ליהוה kodesh laihovah, "Holiness to the Lord."

And the name of the city of my God - As the high priest had on his breastplate the names of the twelve tribes engraved, and these constituted the city or Church of God; Christ here promises that in place of them the twelve apostles, representing the Christian Church, shall be written, which is called the New Jerusalem, and which God has adopted in place of the twelve Jewish tribes.

My new name - The Savior of All; the light that lightens the Gentiles; the Christ; the Anointed One; the only Governor of his Church; and the Redeemer of All mankind.

There is here an intimation that the Christian Church is to endure for ever; and the Christian ministry to last as long as time endures: He shall go no more out for ever.

The Loved Ones Chastened
The fact is, that this world is not the place of punishment. There may now and then be eminent judgments; but as a rule God does not in the present state fully punish any man for sin. He allows the wicked to go on in their wickedness; he throws the reins upon their necks; he lets them go on unbridled in their lusts; some checks of conscience there may be; but these are rather, as monitions than as punishments. And, on the other hand, he casts the Christian down; he gives the most afflictions to the …

"And unto the angel of the church in Sardis write, These things saith He that hath the seven Spirits of God."-- Rev. iii. 1. We do not speak here of the New Testament. Nothing has contributed more to falsify and undermine faith in the Scripture and the orthodox view concerning it than the unhistoric and unnatural practise of considering the Scripture of the Old and the New Testament at the same time. The Old Testament appears first; then came the Word in the flesh; and only after that the Scripture …

Laodicea
We reach, in this last Epistle, the lowest point of Judah's degradation, in that long line of departure from God, from the day Israel left her "first love," even the day of her espousals, when brought forth out of Egypt, down, down through one vast scene of idolatry and judgment, until we find that nation described in the Epistle to the Assembly in Laodicea in a condition of spiritual destitution such as characterised the People in the period of the Minor Prophets. Indeed, so complete is the correspondence, …
