In John 8:31-32, Jesus said, “If you hold to my teaching, you are really my disciples. Then you will know the truth, and the truth will set you free.” When it comes to following Christ, there are some key truths that we need to know beyond the basics. For example, we need to understand who Jesus is and what his mission was while he was here on earth. The Bible tells us that God came to earth and lived in human form as Jesus (John 1:14). Only God could save humanity. So, it makes sense that he had to create a way for us to be restored to him (John 1:29).
