The last book of the Minor Prophets and the Old Testament focus on calling backsliders back to the Lord. The issues address in the book are: the Lord loves His people and will fight for them, the Lord expects to be honored and worshiped with the best of our offerings, the Lord expects His people to treat others respectfully, the Lord tells His people that He is a God of justice, and someday the wicked will reap the Lord's judgment, the Lord calls His people to return to Him and to test Him by giving of a tithe, (10 percent of income), and the Lord reminds His people that it is a blessing to follow Him. The book ends with a challenge to remember the Law of Moses and to keep an eye out for Elijah the Prophet whom the Lord will send. In the New Testament we see that Jesus said in John 5, that Moses wrote about Him, and then in Matthew 17 we learn that the Lord did send Elijah in Jesus' day, and it was John the Baptist. The Old Testament is not complete without the New Testament.
