How do we know Jesus is the blessed man in Psalm 1?

In the sermon, it is emphasized that Jesus Christ is the ultimate embodiment of the blessed man described in Psalm 1. Unlike any other fallen humanity, He never walked in the counsel of the ungodly or stood in the way of sinners; His life was one of complete obedience to God's will. This makes Him the true blessed man, whose delight is in the law of the Lord, as He perfectly honored and fulfilled the law. The blessedness that He earned as the God-man mediator is shared with those who are in Him by faith, thus confirming His central role in Scripture as the blessed figure.
