For it is not you that speak, but the Spirit of your Father who speaks through you.
All Commentaries on Matthew 10:20 Go To Matthew 10
John Chrysostom
AD 407
For lest they should say, How shall we be able to persuade men, when such things are taking place? He bids them be confident as to their defense also. And elsewhere indeed He says, I will give you a mouth and wisdom; Luke 21:15 but here, It is the Spirit of your Father that speaks in you, advancing them unto the dignity of the prophets. Therefore, when He had spoken of the power that was given, then He added also the terrors, the murders, and the slaughters.
