Do you believe they are truly from God?
It is certain that we cannot handle Scripture adequately in the pulpit if our doctrine of Scripture is inadequate.
Conversely, evangelical Christians who have the highest doctrine of Scripture in the Church should be conspicuously the most conscientious preachers. . . . If Scripture were largely a symposium of human ideas, though reflecting the faith of the early Christian communities, and lit up an occasional flash of divine inspiration, then a fairly casual attitude to it would be pardonable.
But in Scripture we are handling the very words of God, “words not taught by human wisdom but taught by the Spirit” (1 Cor. 2:13), God’s words through men’s, his own witness to his own Son, then no trouble should be too great in the study and exposition of them.
