John 17:1

Here we have, I. The circumstances of this prayer, Joh 17:1. Many a solemn prayer Christ made in the days of his flesh (sometimes he continued all night in prayer), but none of his prayers are recorded so fully as this. Observe, 1. The time when he prayed this prayer; when he had spoken these words, had given the foregoing farewell to his disciples, he prayed this prayer in their hearing; so that, (1.) It was a prayer after a sermon; when he had spoken from God to them, he turned to speak to God for them. Note, Those we preach to we must pray for. He that was to prophesy upon the dry bones was also to pray, Come, O breath, and breathe upon them. And the word preached should be prayed over, for God gives the increase. (2.) It was a prayer after sacrament; after Christ and his disciples had eaten the passover and the Lord's supper together, and he had given them a suitable exhortation, he closed the solemnity with this prayer, that God would preserve the good impressions of the ordinance upon them. (3.) It was a family-prayer. Christ's disciples were his family, and, to set a good example before the masters of families, he not only, as the son of Abraham, taught his household (Gen 18:19), but, as a son of David, blessed his household (Sa2 6:20), prayed for them and with them. (4.) It was a parting prayer.
