As Christians, the Lord has provided for us perfect instructions in His Word, the Bible. That Word answers the question, “Who is in charge?” God’s Word carries God’s authority, and those authoritative Scriptures are both clear and fully sufficient, providing all that we need to know of God’s will. Appeal to the Bible, therefore, settles all disputes and controversies within the church. In this first module on systematic theology, we are covering the doctrine of first principles, with special reference to the doctrine of the Holy Scriptures. In the previous lecture, we considered the doctrine of the inspiration of Scripture. We now turn to some of the other properties of Scripture that flow from its inspiration.
