(Taken from the Blessed and Boundless God by George Swinnock)
When we give Him our love, awe, and trust, we actually give Him nothing.
God is a perfect being. When we describe a being as perfect, we mean one of two things. First, a being is perfect when it posses all that is necessary to its kind (that is, its particular species). So we say a man is perfect because he has all that is necessary to a man – a body with all its parts and members, and a soul with all its powers and faculties. Second, a being is perfect when it is impossible to add to it or take from it. That is to say, it is incapable of the least increase or decrease.
God alone is perfect in the second sense. He is absolutely perfect. The sun neither gains anything when the moon is bright nor loses anything when the moon is dark. Likewise, the self-sufficient God neither gains anything from our service nor loses anything by our neglect. He is above the influence of our actions. Our holiness adds nothing to His happiness: “Can a man be profitable unto God, as he that is wise may be profitable unto himself? It is any pleasure to the Almighty, that thou are righteous? Or is it gain to him, that thou makest thy ways perfect?” (Job 22:2-3). As our holiness does not help Him, so our sinfulness does not hurt Him: “If thou sinnest, what doest thou against him? Or if thy transgressions be multiplied, what doest thou unto him? If thou be righteous, what givest thou him? Or what receiveth he of thine hand? Thy wickedness may hurt a man as thou are; and thy righteousness may profit the son of man” (Job 35:6-8). The weapons of unrightouesness might inure flesh and blood, but not the Rock of Ages. He is impenetrable.
God is also above our praises and blessings. What does a fountain gain if people drink its water and commend it rather than despise it? What would God gain if He were to make millions of worlds to magnify Him? What would God lose if there were no world at all? God has given to everyone all that they possess, but not one has ever given anything to Him. When we give Him our love, awe, and trust, we actually give Him nothing. We can give nothing to Him because we owe everything to Him. All of His essential glory admits no increase or decrease.
No other being is absolutely perfect like God. We stand in continual need. We need air to sustain us, food to strengthen us, clothing to cover us, fire to warm us, and sleep to refresh us. We need righteousness to justify us, grace to sanctify us, love to comfort us, and mercy to save us. We are a heap of infirmities, a hospital of diseases, and a bundle of imperfections.
Angels are more perfect than we are, yet they too are imperfect. Something can be added to the,, and something can be taken from them. The highest angel can be higher, the holiest angel holier, and the best angel better. Although the stars differ from each other in brightness, none of them are the sun. Although angels differ from each other in honor and excellency, none of them are God – none of them are absolutely perfect.
