The Bible is the special book of our faith and contains God's teachings that help us know how God wants us to live.
The Deuteronomy passage, known as the Shema, calls us to "love God with all our heart, soul, and might." In Matthew 22:37-39, Jesus repeated the Shema, as being the most important commandment, and then added second commandment, "to love your neighbor as yourself."
The Beatitudes, found in Matthew 5, are not commandments bur rather a description of what is good, or "blessed," in God's eyes.
Scriptures: Deuteronomy 6:4-5, Matthew 5:1-12, Matthew 22:37-39
