The scriptural revelations of the divine Name are always the basis of intensely practical admonition. The Bible does not think it worth while to proclaim the Name of God without building on the proclamation promises or commandments. There is no 'mere theology' in Scripture; and it does not speak of 'attributes,' nor give dry abstractions of infinitude, eternity, omniscience, unchangeableness, but lays stress on the personality of God, which is so apt to escape us in these abstract conceptions, and thus teaches us to think of this personal God our Father, as infinite, eternal, knowing all things, and never changing. There is all the difference in our attitude towards the very same truth if we think of the unchangeableness of God, or if we think that our Father God is unchangeable. In our text the thought of Him as unchanging comes into view as the foundation of the continuance of the unfaithful sons of Jacob in their privileges and in their very lives. 'I am the Lord,' Jehovah, the Self-existent, the Eternal whose being is not under the limitations of succession and time. 'Because I am Jehovah, I change not'; and because Jehovah changes not, therefore our finite and mortal selves abide, and our infinite and sinful selves are still the objects of His steadfast love. Let us consider, first, the unchangeable God, and second, the unchanging God as the foundation of our changeful lives. I. The unchangeable God. In the great covenant-name Jehovah there is revealed an existence which reverses all that we know of finite and progressive being, or finite and mortal being, or finite and variable nature. With us there are mutations arising from physical nature. The material must needs be subject to laws of growth and decadence. Our spiritual nature is subject to changes arising from the advancement in knowledge. Our moral nature is subject to fluctuations; circumstances play upon us, and 'nothing continueth in one stay.' Change is the condition of life. It means growth and happiness; it belongs to the perfection of creatures. But the unchangeableness of God is the negation of all imperfection, it is the negation of all dependence on circumstances, it is the negation of all possibility of decay or exhaustion, it is the negation of all caprice. It is the assurance that His is an underived, self-dependent being, and that with Him is the fountain of light; it is the assurance that, raised above the limits of time and the succession of events, He is in the eternal present, where all things that were and are, and are to come, stand naked and open. It is the assurance that the calm might of His eternal will acts, not in spasms of successive volitions preceded by a period of indecision and equilibrium between contending motives, but is one continuous uniform energy, never beginning, never bending, never ending; that the purpose of His will is 'the eternal purpose which He hath purposed in Himself.' It is the assurance that the clear vision of
