Was there not a severe pestilence in Israel?

II Samuel 24:15 So the LORD sent a pestilence upon Israel from the morning even to the time appointed: and there died of the people from Dan even to Beersheba seventy thousand men.
 16 And when the angel stretched out his hand upon Jerusalem to destroy it, the LORD repented him of the evil, and said to the angel that destroyed the people, It is enough: stay now thine hand. And the angel of the LORD was by the threshingplace of Araunah the Jebusite.
 17 And David spake unto the LORD when he saw the angel that smote the people, and said, Lo, I have sinned, and I have done wickedly: but these sheep, what have they done? let thine hand, I pray thee, be against me, and against my father's house.

Did not the LORD stop it before it killed any more?
So, are then not we, who are called by his name, the ones who could be calling on Jesus to do exactly that?

II Chronicles 7:13 If I shut up heaven that there be no rain, or if I command the locusts to devour the land, or if I send pestilence among my people;
 14 If my people, which are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways; then will I hear from heaven, and will forgive their sin, and will heal their land.

Is not our nation sick spiritually, and now sick physically?
So why are we not really humbling ourselves, or truly praying, or earnestly seeking his face, or apparently not turning from our wicked ways?
If we actually were, would not Jesus then be healing our land?
