This is the first in a series of Christianity 101 studies. Each of the basic and foundational doctrines of Christianity as listed in the book of Hebrews 6:1-3 will be covered through the series of Bible studies. This unit's focus is on having faith in God, and understanding the Bible. Beginning with the question of God's existence this will explain a number of mysteries, falsehoods, and misunderstood beliefs about God and the Bible. Here are a few of the questions you will find answered in this Christianity 101 Unit 1 book. Does God exist? How can we know which one is the right God? Who wrote the Bible? Can we trust the Bible? Why are there so many different translations? How can we know which one is best to use? Where did they all come from? What are the devices of Satan? How can we be a strong witness? How can we properly understand the Bible? What about contradictions? What and who is the trinity?
