This article provides a series of questions and answers that engage with the authority of Scripture and how it is the only rule of faith and practice.

The author contends that the doctrine of predestination is the one that exalts God the most, for faith depends on God's eternal choice.

He argues in the end that the doctrine of predestination ascribes to God the greatest supremacy and glory.
