And I knew that thou hearest me always: but because of the people which stand by I said it, that they may believe that thou hast sent me.

People's New Testament

11:42 Thou hearest me always. Even in Gethsemane, when the cup was not taken away (Mt 26:39,42,44 Mr 14:36,39).

Jamieson-Fausset-Brown Bible Commentary

42. And-rather, "Yet."

I knew that thou hearest me always, but because of the people that stand by I said it, that they might believe that thou hast sent me-Instead of praying now, He simply gives thanks for answer to prayer offered ere He left Perea, and adds that His doing even this, in the audience of the people, was not from any doubt of the prevalency of His prayers in any case, but to show the people that He did nothing without His Father, but all by direct communication with Him.

Matthew Henry's Concise Commentary

11:33-46 Christ's tender sympathy with these afflicted friends, appeared by the troubles of his spirit. In all the afflictions of believers he is afflicted. His concern for them was shown by his kind inquiry after the remains of his deceased friend. Being found in fashion as a man, he acts in the way and manner of the sons of men. It was shown by his tears. He was a man of sorrows, and acquainted with grief. Tears of compassion resemble those of Christ. But Christ never approved that sensibility of which many are proud, while they weep at mere tales of distress, but are hardened to real woe. He sets us an example to withdraw from scenes of giddy mirth, that we may comfort the afflicted. And we have not a High Priest who cannot be touched with a feeling of our infirmities. It is a good step toward raising a soul to spiritual life, when the stone is taken away, when prejudices are removed, and got over, and way is made for the word to enter the heart. If we take Christ's word, and rely on his power and faithfulness, we shall see the glory of God, and be happy in the sight. Our Lord Jesus has taught us, by his own example, to call God Father, in prayer, and to draw nigh to him as children to a father, with humble reverence, yet with holy boldness. He openly made this address to God, with uplifted eyes and loud voice, that they might be convinced the Father had sent him as his beloved Son into the world. He could have raised Lazarus by the silent exertion of his power and will, and the unseen working of the Spirit of life; but he did it by a loud call. This was a figure of the gospel call, by which dead souls are brought out of the grave of sin: and of the sound of the archangel's trumpet at the last day, with which all that sleep in the dust shall be awakened, and summoned before the great tribunal. The grave of sin and this world, is no place for those whom Christ has quickened; they must come forth. Lazarus was thoroughly revived, and returned not only to life, but to health. The sinner cannot quicken his own soul, but he is to use the means of grace; the believer cannot sanctify himself, but he is to lay aside every weight and hinderance. We cannot convert our relatives and friends, but we should instruct, warn, and invite them.
