General Revelation & Natural Theology

While Scripture is the supreme source of revelation concerning God, it is not the only source. The Bible tells us that we can clearly see God’s eternal power and divine nature in the created realm.

Providence

The secular mind-set says that God is a spectator in heaven with no control over what happens on earth.

In this lesson, Dr. Sproul highlights that God is actively involved in preserving His creation, even working His will through our intentional decisions.
