The Almighty God, the Lord, can only be praised by His created people for He is King, He is great and high above the people, He is awesome, but above all He is Holy. We, as created mortals, cannot think of God as being anything other than “Holy Other” or also “wholly other.” He is so unique in His holiness that he is so different and special and so far above and beyond us as to be unapproachable. God can only be feared and worshiped but not known. We can’t relate.
But He loved people, so He took the initiative to come to us and reveal Himself in ways that made Him available. Moses and Aaron and Samuel, for example, were intercessors for us and the Lord heard their prsyers. He does this for us finally and continually through our great High Priest, Jesus Christ.
And through Him, in His Name, Holy God hears us. God forgives Moses, Aaron and Samuel, and us. Thus He can answer prayers. But note that this God also takes vengeance on, justly judges, their wrongdoings.
A Loving God forgives Sin; a Holy God judges it. In the Cross He did both. The Supreme Holy God deals with us through the Cross.
