This simple statement in itself constitutes a definite and complete system of theology.It fixes clearly and distinctly the nature and character of God. It sums up the Truth of Being. It tells all that man needs to know about God, and about himself, and about his neighbor. Anything that is added to this can only be by way of commentary, and is more likely than not to complicate and obscure the true meaning of the text. Oliver Wendell Holmes said: “My religion is summed up in the first two words of the Lord’s Prayer,” and most of us will find ourselves in full agreement with him….
… If you would meditate upon this fact, until you had some degree of understanding of what it really means, most of your difficulties and physical ailments would disappear, for they are rooted and grounded in fear. The underlying cause of all trouble is fear. If only you could realize to some extent that Omnipotent Wisdom is your living, loving Father, most of your fears would go. If you could realize it completely, every negative thing in your life would vanish away, and you would demonstrate perfection in every phase. Now you see the object that Jesus had in mind when he placed this clause first.
