Greed is one of the biggest driving forces of evil in our world today, and in history. 1 Timothy 6:10 says “The love of money is the root of all kinds of evil.” This is very true.
Man’s solution to sin in the world is politics, God’s solution is Christ on the cross. Laws can restrain evil but the cross can crucify it.
Romans 8:3 For what the law was powerless to do in that it was weakened by the sinful nature, God did by sending his own Son in the likeness of sinful man to be a sin offering. And so he condemned sin in sinful man, 4 in order that the righteous requirements of the law might be fully met in us, who do not live according to the sinful nature but according to the Spirit.
