The Deity of Jesus Proven from Hebrews

"Of old You laid the foundation of the earth, 

And the heavens are the work of Your hands. 

They will perish, but You will remain; 

They will all wear out like a garment. 

You will change them like a robe, and they will pass away, 

But You are the same, and Your years have no end." 

- Psalm 102:25-27 

The verses above were penned by the Holy Spirit through an unnamed poet. We are told of him in the subtitle only that he was "one afflicted," but not by what. It continues, "when he was faint and pours out his complaint before the Lord." Indeed, the psalm is full of pathos, and we should be encouraged by that example. Jesus is ready to hear all of our human emotions, not just happy ones, as is sometimes suggested by popular TV preachers. 

These verses are then quoted in Hebrews 1:10-12, and explicitly applied to the Son, that is, to Jesus in His divinity (verse 8), in His role as co-Creator with the Father.

In the original passage, we are given no specific information to which divine Person the passage is addressed. In isolation, it could be taken as addressed to the Father. However, we have a hint, made explicit by the author of Hebrews, that it is addressed to the preincarnate Son because the psalmist explicitly addresses his complaints to Jehovah (verse 1), the name by which He was known to His Old Covenant people. However, the sects can pretend not to see that, whether to support the Arianism of the Jehovah's Witnesses or the tritheism of the  Mormons or the Sabellianism of the Oneness Pentecostals, or any other denial of the full deity of Christ. 

Yet, when we look at the quote in Hebrews, all of those quibbling voices are quelled, as that author makes explicit what is implied in the original: the Lord of whom the Psalmist speaks is none other than the Son, our Lord Jesus Christ.
