I’ve said this before, but theology is an issue of finding your balance. This can happen in various ways, but one of the simplest is to pick out one element of biblical truth and elevate it above all others, ignoring, or sidelining important balancing themes. For instance, some have issues with accounts of salvation that emphasize, or indeed, merely teach that God does not accomplish his forgiveness apart from atonement. Is he not a loving Father? Do not fathers forgive all the time without requiring payment or retribution? If even human fathers can do so, how can our heavenly Father be any less merciful or gracious by requiring satisfaction for sins?
Bavinck shows us the problem with that sort of thing:
God is most certainly the Father of humankind, but this name is far from describing the entire relationship in which God stands to his creatures. He is also Creator, Maintainer, Ruler, Sovereign, Lawgiver, Judge, and so on, and it is one-sided and conducive to error if one takes one of these names—disregarding all the others—to be the full revelation of God. Thus, in relation to sin, God is not just a creator or injured party who can cancel the debt and forgive as well as forget the insult but is himself the giver, protector, and avenger of the law, righteousness in person, and as such he cannot forgive sin without atonement (Heb. 9:22). In that capacity he cannot nullify the just demands of the law, for we are not speaking here about personal or private rights, which one can relinquish, but about the righteousness, that is, the perfections and honor of God himself. Against this idea one could appeal to the prerogative of pardon that an earthly government frequently exercises, but this prerogative of pardon is only given to it because it is fallible and in many cases inflicts a penalty that is too severe or even undeserved. In God something like that cannot happen. He is righteousness in person, does not need to restore justice or nullify it by grace, but lets both justice and grace come to expression in the cross of Christ.
-Herman Bavinck, Reformed Dogmatics Volume 3: Sin and Salvation in Christ, pp. 372-373
Of course, one can tip the balance in the other direction and only fixate on God’s role as judge or king and forget that he is the Father who is passionately concerned to forgive. God is not begrudging in securing atonement, but gloriously willing to save sinners even as they reject him (Romans 5:6-8). Still, whichever way it happens, both make the mistake of flattening God’s relationship with his creatures by failing to account for each part of the crucial biblical imagery by which he reveals himself to us.
In other words, God gave us more than one beautiful name for himself in the Scriptures. We need to make sure we understand and worship him in light of all of them.
