How do we know that the teachings of Christ are true?

The certainty of Christ's teachings is grounded in the Scriptures, as declared by the apostles. In 1 John, John stresses that what he and others have proclaimed about Jesus - that He is the eternal Son of God and the Lamb who takes away the sin of the world - must be recognized and held tightly. This approach to understanding truth hinges on a relationship with Jesus as the source of life. Authentic knowledge of the truth is not merely intellectual but is lived out through obedience to His commands. The transformative power of these teachings is evidenced in the lives of believers who obey and thus affirm the truth of such teachings.
