Wisdom is knowing that, as Packer puts it, “our own intellectual competence is not the test and measure of divine truth.” He goes on: It is not for us to stop believing because we lack understanding, or to postpone believing till we can get understanding, but to believe in order that we may understand; as Augustine said, “unless you believe, you will not understand.” Faith first, sight afterwards, is God’s order, not vice versa; and the proof of the sincerity of our faith is our willingness to have it so.3
