19. The angel of the Lord. The Lord brought the apostles out of prison, not because he would rid them quite out of the hands of their enemies, for he suffered them afterwards to be brought back again, and to be beaten with rods; but he meant to declare, by this miracle, that they were in his hand and tuition, to the end he might maintain the credit of the gospel; partly that the Church might have another confirmation thereby, partly that the wicked might be left without excuse wherefore we must not hope always, nay, we must not always desire that God will deliver us from death; but we must be content with this one thing, that our life is defended by his hand, so far as is expedient. In that he useth the ministry of an angel, in this he doth according to his common custom; for he testifieth every where in the Scriptures, that the angels are ministers of his goodness towards us. Neither is that a vain speculation, for this is a profitable help for our infirmity, that we know that not only God doth care for us, but also that the heavenly spirits do watch for our safety. Again, this was no small pledge of God’s love towards us, that the creatures of all other most noble are appointed to have regard of our safety. The angel openeth the prison in the night, because he would not work the miracle when the wicked might see him, although he would have the same being wrought known by the event itself.
