How important is Faith? To you, to me, to God?
Mat 23:23 "Woe to you, scribes and Pharisees, hypocrites! For you pay tithe of mint and anise and cummin, and have neglected the weightier matters of the law: justice and mercy and faith. These you ought to have done, without leaving the others undone.
Jesus identifies what the weightier matters are: justice and mercy and faith.
