I will sing of mercy and judgment: unto thee, O LORD, will I sing.
I will behave myself wisely in a perfect way. O when wilt thou come unto me? I will walk within my house with a perfect heart.
I will set no wicked thing before mine eyes: I hate the work of them that turn aside; it shall not cleave to me.
A froward heart shall depart from me: I will not know a wicked person.
Whoso privily slandereth his neighbour, him will I cut off: him that hath an high look and a proud heart will not I suffer.
Mine eyes shall be upon the faithful of the land, that they may dwell with me: he that walketh in a perfect way, he shall serve me.
He that worketh deceit shall not dwell within my house: he that telleth lies shall not tarry in my sight.
I will early destroy all the wicked of the land; that I may cut off all wicked doers from the city of the LORD.
– Psalm 101
Jesus is the Son of David. And Jesus is the Son of God. And the Son of Man. And the Christ. Now, David was also the Son of God. It’s a title for the king of Israel, Son of God. Hence it’s use in the enthronement psalm, psalm 2. And Christ means anointed; David was also anointed; David was also a Christ.
And David was the man after God’s own heart. God really liked David, and apparently liked the way he led Israel. He did sin and that grievously, but those were rather isolated incidents; he repented. In general, David cared about what God cared about.
Jesus takes freely of the psalms and applies them to himself. He seems to think they were written about him. But they seem pretty obviously to us to have been written by David about David’s life.
Now, if Jesus is the Son of David and is the inheritor of David’s office, then it would seem to follow that Jesus would face many of the same kinds of situations that David did. He would have David’s same responsibilities. He would have enemies like David had enemies. And if David was the man after God’s own heart, then he cared about the same things that Jesus does. And hence what was true of David is going to be largely also true of Jesus.
Psalm 101 paints a picture of some of David’s daily concerns in the office of King of Israel. Jesus probably has the sames concerns and care. He was sent, after all, not to bring peace but a sword. And it is he who baptizes with fire and whose fan is in his hand, who shall burn up the chaff with unquenchable fire. And who shall abide the day of his coming? Or who shall stand when he appeareth? For he shall return as a thief in the night, and woe to that servant who is asleep at his coming.
