THE PERFECTION OF GOD
The man of God of the last century, A.W. Tozer, said it this way, "If God is self-existent, he must be also self-sufficient; and if he has power, he, being infinite, must have all power. If he possesses knowledge, his infinitude assures us that he possesses all knowledge.
Similarly, his immutability presupposes his faithfulness. If he is unchanging, it follows that he could not be unfaithful, since that would require him to change. Any failure within the divine character would argue imperfection and, since God is perfect, it could not occur. Thus the attributes explain each other and prove that they are but glimpses the mind enjoys of the absolutely perfect Godhead."
