This episode reviews Dave's four phases of his life:
Annointed, but not official in man's eyes & chased by Saul
King who conquers, unifies & builds
Absalom's rebellion
The final years
There are lots of great stories during the life of David, and they're fun to tell and fun to hear. But we should not allow the drama to distract us from the value of the teachings: they apply to our lives. David's character in faithfulness and sin is revealed. He sets an example for repentance like no other. He is unique among leaders as one who responds to God's prophet with his complete repentance and subjection, unlike most leaders in the bible (or nowadays).
Dave's character shines in the Psalms, where we get a unique and beautiful view into the soul of the man who wrote them. They are the inspired word of God, in that they're an accurate reflection of what Dave (and others) wrote, and they wrote what they felt; but - the feelings they represent reveal the truth of the writer's heart, not necessarily God's heart. They also must not be used to 'prove' stuff doctrinally, for that is terrible, awful biblical interpretation!
Now it's the spring of the year, when kings go to war. What season is it in your life? Will you seek out someone to serve, to love, to make stronger, and to protect from harm? Will you be a good shepherd, or a lazy one?
I leave you with this prayer for the new year (2012): that in some way you may be provoked by David's sin to not put yourself in similar temptation. That you may go, make disciples, baptize them, and teach them to obey (in that order) ... and that you'll make it your ambition to accomplish it to the glory of God.
