Scripture teaches that God himself is logical. In
the first place. His Word is truth (John 17:17), and truth means nothing
if it is not opposed to falsehood. Therefore His Word is noncontradictory.
Furthermore, God does not break His promises (2 Cor. 1:20); He does not deny
himself (2 Tim. 2:13); He does not lie (Heb. 6:18; Tit. 1:2). At the very
least, those expressions mean that God does not do, say, or believe the
contradictory of what He says to us. The same conclusion follows from the
biblical teaching concerning the holiness of God. Holiness means that
there is nothing in God that contradicts His perfection (including His
truth). Does God, then, observe the law of noncontradiction? Not in the sense
that this law is somehow higher than God himself. Rather, God is himself
noncontradictory and is therefore himself the criterion of logical consistency and
implication. Logic is an attribute of God, as are justice, mercy, wisdom,
knowledge. As such, God is a model for us. We, as His image, are to imitate His
truth, His promise-keeping. Thus we too are to be noncontradictory.
Therefore the Westminster Confession of Faith is
correct when it says (I, vi) that the whole counsel of God is found not only in
what Scripture explicitly teaches but also among those things that “by good and
necessary consequence may be deducted from Scripture.” (John M. Frame, The
Doctrine of the Knowledge of God [A Theology of Lordship; Phillipsburg, N.J.:
Presbyterian and Reformed, 1987], 253)
