Though Jesus is not of the line of Levi, He is entitled to the office of high priest after the order of Melchizedek. Abraham’s payment of a tithe shows that Melchizedek was greater than he. Like Abraham, we are obligated to tithe to our priest-king Jesus. People often crave the accreditation of men idolatrously. All institutions are to be established under the authority of God. So in every area of activity, we are to seek the approval of God, and not men.
