'...biblical discernment looks beyond the will of God to the truth of God. We can only know God's will when we first know God's truth, for what God desires and requires of us must always be consistent with his character. Wise decisions are those that are made on the firm basis of what is true about God and, thus, what is true about the world, about life, and about ourselves. Those who make decisions that honour God are those who have invested effort in studying what God says to be true.'
Tim Challies, The Discipline of Spiritual Discernment, p. 54.
