WISDOM FROM THE OLD TESTAMENT
"In the spring, at the time when kings go off to war, Joab led out the armed forces. He laid waste the land of the Ammonites and went to Rabbah and besieged it, but David remained in Jerusalem. Joab attacked Rabbah and left it in ruins." 1 Chron. 20:1 (emphasis added). Sad but true, that even when God was appointing kings Godself, that the glory associated with war lured kings into have a time when they went off to it.
There is a pretty typical struggle between faith and the law that plays out in Paul's letters. According to Paul, faith, or what seems to be the law of God that is not the same as the written law, has always been there. Jesus was shedding light on what already was. Paul cites to Abraham and David in support of Jesus' Way. But don't forget, Paul does not claim that faith replaces the law. Rather it upholds it. Rom. 3:31-4:12.
