So far, the apostle John has given us two ways to test whether a prophet is from God or not. Now, he introduces the third test we may use to evaluate the spirit by which a ‘prophet’ speaks. If a prophet really speaks for God, this will first be evident in what he teaches about Christ. Secondly, it will also be obvious in the respect he shows for the teaching of Christ’s Apostles. In the third place, it will be evident in the reflection of the nature of God in his life and teaching.
