William Burkitt on John 16:31

In the foregoing verse, the apostles made a full profession of their faith in Christ's divinity, and in Christ's omnipotency: Now are we sure that thou knowest all things, and that thou camest forth from God.

In this verse Christ intimates to them that their faith should be put to a great trial very shortly, namely, when his sufferings came on: and that then they should all forsake him, and take care of themselves: Ye shalt be scattered and leave me alone.

Learn hence, 1. That Christ was forsaken and left alone by his own disciples in the day of his greatest distress and danger.

2. That when the disciples left Christ, they were scattered every one to his own.

3. That when all forsook Christ, and left him alone, he was far from being simply alone, because God was with him: Ye shall leave me alone, and yet I am not alone, because the Father is with me.

God was with Christ, and will be with Christians, in a suffering hour, in his essential presence, in his gracious and supporting presence: He that sent me, says Christ, is with me: the Father hath not left me alone: for I do always those things that please my Father.
