John 14:1

Let not your heart be troubled - After having answered St. Peter's question, he addresses himself again to his disciples, and tells them not to be afflicted at his leaving them, nor to lose courage because of what he said concerning Peter's denying him; that if they reposed their confidence in God, he would protect them; and that, howsoever they might see him treated, they should believe in him more firmly, as his sufferings, death, and resurrection should be to them the most positive proof of his being the Messiah, the Savior of the world.

Ye believe in God, believe also in me - It is best to read both the verbs in the imperative mood: - Place your confidence in God, and in me as the Mediator between God and man, John 14:12-14 ; and expect the utmost support from God; but expect it all through me. The disciples began to lose all hope of a secular kingdom, and were discouraged in consequence: Christ promises them a spiritual and heavenly inheritance, and thus lifts up their drooping hearts.
