Matthew Henry on 1 Peter 1:10-12

Jesus Christ was the main subject of the prophets' studies. Their inquiry into the sufferings of Christ and the glories that should follow, would lead to a view of the whole gospel, the sum whereof is, That Christ Jesus was delivered for our offences, and raised again for our justification. God is pleased to answer our necessities rather than our requests. The doctrine of the prophets, and that of the apostles, exactly agree, as coming from the same Spirit of God. The gospel is the ministration of the Spirit; its success depends upon his operation and blessing. Let us then search diligently those Scriptures which contain the doctrines of salvation.
