Show me the foundation of this amazing promise. So in its Old Testament context the declaration of God's absolute freedom to be gracious to whomever he pleases is intended to give Moses hope and assurance that God indeed can and will be gracious to the stiff-necked people of Israel and go with them to the promised land. The Bible never gives us glimpses of God's nature merely for intellectual discussion. It opens the name and glory of God to our understanding in order to help us revere God and love him and trust him and obey him. The deepest doctrines of God have to do with everyday life.
Theology is the most relevant and practical of all the human disciplines.
If that isn't our experience it's either because our theology is untrue, or because we go about it in a spirit of irreverence and make a game of it. The doctrines of God revealed in the Bible are of immense personal, practical and eternal importance. O how we need to study the name and glory of God. The practical relevance of God's freedom for Moses leads to some practical implications for us too. But before we unpack some of these, let's define our doctrine more precisely and survey its wider Biblical foundation.
