WHO INCITED DAVID TO TAKE THE CENSUS? GOD OR SATAN?

II Samuel 24:1 And again the anger of the LORD was kindled against Israel, and he moved David against them to say, Go, number Israel and Judah. (KJV) I Chronicles 21:1 And Satan stood up against Israel, and provoked David to number Israel. (KJV)

This is not a contradiction because both are true.  Like in many cases throughout the Bible, such as the temptation of Jesus in the desert and Peter's denial of the Lord, these actions were done under the influence of satan, but with God's stamp of approval as well, since God knew that the result would ultimately favor Him.  In this case, David's pride was driving him further from God, and God knew that David needed to be punished so that he could learn to rely on God, and not on himself.  God allowed David's disobedience to go ahead, knowing the negative affect it would have upon his self-pride.  Not a contradiction.
