0 How do we know that all Scripture is inspired of God and beneficial to us?

The Bible tells us that all Scripture is inspired of God and beneficial.

2 Peter 1:20-21 says, "Above all, you must understand that no prophecy of Scripture came about by the prophet's own interpretation. For prophecy never had its origin in the will of man, but men spoke from God as they were carried along by the Holy Spirit."

0 Christian teaching - How does it differ from other religions?

How does Christian teaching differ from the teachings of other religions? The teaching of Christianity is totally unique in that it has a Person as its focal point. The object of Christian teaching is Jesus Christ Himself. Unlike other religions, it is not dogma or doctrine as an end in itself. The truths that Christians expound dogmatically, the doctrines that make up the "what we believe" charters of Christian churches all point to the Lord of all.
