Charles Spurgeon Commentary Revelation 1:9

"I John, your brother and partaker with you in tribulation and kingdom and patience [which are] in Jesus, was in the isle that is called Patmos, for the word of God and the testimony of Jesus." — Revelation 1:9 (ASV)

I John, who also am your brother,

How sweetly this sounds. This is a man that has seen and heard God. This is a man who is full of visions, who has beheld the broken seals and the poured out vials; the man that is familiar with the infinite. I, John, who also am your brother.

And companion in tribulation, and in the kingdom and patience of Jesus Christ, was in the island that is called Patmos, for the word of God, and for the testimony of Jesus Christ.

That is a wondrous linking, is it not, in this verse? — the kingdom and patience. You must have the cross and the crown together. We get the kingdom of Christ, but not without the passion of Christ. There is the cross marked on all the treasure trove that we find in Christ. It is not genuine if it is not marked with the cross.

The kingdom and patience of Jesus Christ.
