R.C. Sproul admits that when he approaches his conception of God, it is through his own presuppositions (Eisegesis rather than Exegesis).

One might think that someone committed to the Bible would finish his concluding statement differently:

“In reformed theology we constantly test our doctrine by going back to”
A. Our fundamental understanding of the character of God
B. The Bible

R.C. Sproul chooses “A”.
