The familiar picture of God as often torn between His justice and His mercy is altogether false to the facts. To think of God as inclining first toward one and then toward another of His attributes is to imagine a God who is unsure of Himself, frustrated and emotionally unstable, which of course is to say that the one of whom we are thinking is not the true God at all but a weak, mental reflection of Him badly out of focus.
God being who He is, cannot cease to be what He is, and being what He is, He cannot act out of character with Himself. He is at once faithful and immutable, so all His words and acts must be and remain faithful. Men become unfaithful out of desire, fear, weakness, loss of interest, or because of some strong influence from without. Obviously none of these forces can affect God in any way. He is His own reason for all He is and does. He cannot be compelled from without, but ever speaks and acts from within Himself by His own sovereign will as it pleases Him.
I think it might be demonstrated that almost every heresy that has afflicted the church through the years has arisen from believing about God things that are not true, or from overemphasizing certain true things so as to obscure other things equally true. To magnify any attribute to the exclusion of another is to head straight for one of the dismal swamps of theology; and yet we are all constantly tempted to do just that.
