True Christianity is much more than membership in one of the many religions. Jesus himself foretold the rise of counterfeit Christians. (Matthew 7:22, 23)
Jesus told his followers: “You are my friends if you do what I am commanding you.” (John 15:14) Since Jesus’ teachings affected all aspects of their lives, Christ’s disciples initially referred to their religion as “The Way.” (Acts 9:2) Soon thereafter, “[they] were by divine providence called Christians.” (Acts 11:26)
With this in mind, Jesus not only fulfilled scripture but continuously quoted the Scriptures because the Bible is the ultimate authority and guide on how people should live their lives. But he humbly made sure to attribute all of this wisdom to his Father:
"What I teach is not mine, but belongs to him that sent me." (John 7:16)
This is because the Bible itself shows that:
"All Scripture is inspired of God and beneficial for teaching, for reproving, for setting things straight, for disciplining in righteousness, that the man of God may be fully competent, completely equipped for every good work." (2 Tim. 3:16)
