I appreciate these words from Wayne Grudem in his Systematic Theology: An Introduction to Biblical Doctrine
We Should Study Systematic Theology With Rejoicing and Praise. The study of theology is not merely a theoretical exercise of the intellect. It is a study of the living God, and of the wonders of all his works in creation and redemption. We cannot study this subject dispassionately! We must love all that God is, all that he says and all that he does.
Grudem captures it well: “Doctrine is to be felt at the emotional level as well as understood at the intellectual level.”
