Ranting on 1 Samuel

So just heard the dean of a certain Australian college give a series of sermons on 1 Samuel as training on how to preach OT narratives in a Christ-focused manner:

which to him means explaining the passage in detail and then putting 1-3 minutes of Jesus at the end...
does that qualify as preaching Christ?

For example, 1 Sam 13,
Amnon & Tamar... explain whole story, let it come out in feeling...
then at the end Jesus is the true son of David who will live the way David never could
unlike the real sons of David which brought out the murderer and rapist in him

ok i guess.. but is that all we've got??

what about this...

as we trace how sin works and affects the prince and his half-sister-bride

we then come to trace the faithful prince, with his sister, his bride,

Song of Solomon 4:9 You have captivated my heart, my sister, my bride; you have captivated my heart with one glance of your eyes, with one jewel of your necklace.

he then knows how to wait for love, for if he advances on her too soon, she will reject him and be his tool, not his helper, and he indeed will be like all the other fools who: stir up or awaken love (before)  it pleases.

No, He will woo her, and die for her, instead of murdering her husband.. to allow her to open up slowly and surely, 

then he will take his (half) sister, bride - according to the King's command, into their mother's bed chamber 

forever

or something like that?
