Deuteronomy is the second to last book of the Bible, and written by the half-brother of Jesus. It urges Christians to keep away from false teaching, and to stay the course in the Christian faith.

Jude contains one of the most famous doxologies in the Bible.
“To him who is able to keep you from stumbling and to present you before his glorious presence without fault and with great joy—  to the only God our Saviour be glory, majesty, power and authority, through Jesus Christ our Lord, before all ages, now and forevermore! Amen.”
