There are four Gospels, each recounting the birth, life, death, and resurrection of Jesus Christ. They should be understood as a whole; that is, they complement each other, but there are certain details that you will only find in one of these Gospels.
The first three (Matthew, Mark, and Luke) are called the Synoptic Gospels because they share many common accounts, which is not the case with the fourth Gospel, John.
The Book of Acts of the Apostles is an account of the founding of the early church. The book begins with the ascension of Jesus into heaven and ends with the gospel being spread throughout Asia, in fulfillment of the prophecy of Jesus Christ.
