Luke 20:45

For as all the faithful are the children of Abraham, and the Divine promise of being a God to him and his seed is entailed upon them, it implies their continued existence and happiness in a future state as much as Abraham's. And as the body is an essential part of man, it implies both his resurrection and theirs; and so overthrows the entire scheme of the Sadducean doctrine.

Note, Christ was a preacher of his own gospel. He not only purchased the salvation for us, but published it to us, which is a great confirmation of the truth of the gospel, and gives abundant encouragement to us to receive it, for it is a sign that the heart of Christ was much upon it, to have it received.

Let us observe in this passage — what striking testimony to Christ's divinity, the book of Psalms contains. We read that after patiently replying to the attacks of His enemies, our Lord in turn propounds a question to them. He asks them to explain an expression in the hundred and tenth Psalm, where David speaks of the Messiah as his Lord. To this question the Scribes could find no answer.

We read that after patiently replying to the attacks of His enemies, our Lord in turn propounds a question to them. He asks them to explain an expression in the hundred and tenth Psalm, where David speaks of the Messiah as his Lord. To this question the Scribes could find no answer. They did not see the mighty truth — that Messiah was to be God as well as man; and that while as man , He was to be David's son — as God , He was to be David's Lord. Their ignorance of Scripture was thus exposed before all the people. Professing themselves to be instructors of others and possessors of the key of knowledge — they were proved unable to explain what their own Scriptures contained. We may well believe that of all the defeats which our Lord's malicious enemies met with — none galled them more than this. Nothing so abashes the pride of man — as to be publicly proved ignorant of that which he imagines is his own particular department of knowledge. We have probably little idea how much deep truth is contained in the book of Psalms. No part of the Bible perhaps is better known in the letter — and none so little understood in the spirit . We err greatly, if we suppose that it is nothing but a record of David's feelings, of David's experience, David's praises, and David's prayers. The hand that held the pen was generally David's — but the subject matter was often something far deeper and higher than the history of the son of Jesse. The book of Psalms, in a word, is a book full of Christ — Christ suffering — Christ in humiliation — Christ dying — Christ rising again — Christ coming the second time — Christ reigning over all. Both of Christ's advents are here: the advent in suffering to bear the cross — and the advent in power to wear the crown.
