For our Bible study on the common faith, the first item we cover is the Bible. The Bible is where we find the word of God and the contents of our faith.
Although we may use ministry books that open the Bible to us and help us to understand the Bible, the Bible is always the final authority on any matter.
We should be able to answer questions about the Bible. Using verses in the Bible, can you show what the origin of the Bible is? How about this question: Is the Bible really that good? What can it do for us? The attached slides reveal the answers.
