“There are few lines quite so poignantly applicable to the theologian’s craft as those of the medieval poet Geoffrey Chaucer, who wrote of ‘The life so short, the craft so long to learn. The attempt so hard, the victory so keen.’
It is, in fact, surprising that the thought should ever cross our minds that the theological undertaking could be otherwise, for understanding– understanding of God, of ourselves, of the world– comes so slowly, so painfully slowly, that ‘life’s’ summer passes and the winter arrives long before this fruit is ripe to be picked.
Or so it seems. And that, perhaps, is why we are so fiercely tempted to turn theology into a technique that we can use to produce a more efficiently gained and bountiful knowledge of God!
God, however, is not like the periodic table.
He is not a quantity that can be ‘mastered’ even though He can be known; and though He has revealed Himself with clarity, the depth of our understanding of Him is measured, not by the speed with which theological knowledge is processed, but by the quality of our determination to own His ownership of us through Christ in thought, word, and deed.
Theology is the sustained effort to know the character, will, and acts of the triune God as He has disclosed and interpreted these for His people in Scripture, to formulate these in a systematic way in order that we might know Him, learn to think our thoughts after Him, live our lives in His world on His terms, and by thought and action projection His truth into our own time and culture.
It is therefore a synthetic activity whose center is the understanding of God, whose horizon is as wide as life itself, and whose mission echoes the mission of God Himself, which is to gather together in Christ a progeny as numerous as the stars above (Gen. 15:1-6; Gal. 3:6-16).”
