12:1-12 A firm belief of the doctrine of God's universal providence, and the extent of it, would satisfy us when in peril, and encourage us to trust God in the way of duty. Providence takes notice of the meanest creatures, even of the sparrows, and therefore of the smallest interests of the disciples of Christ. Those who confess Christ now, shall be owned by him in the great day, before the angels of God. To deter us from denying Christ, and deserting his truths and ways, we are here assured that those who deny Christ, though they may thus save life itself, and though they may gain a kingdom by it, will be great losers at last; for Christ will not know them, will not own them, nor show them favour. But let no trembling, penitent backslider doubt of obtaining forgiveness. This is far different from the determined enmity that is blasphemy against the Holy Ghost, which shall never be forgiven, because it will never be repented of.See the notes at Matthew 10:17-20. 10. Son of man … Holy Ghost—(See on [1648]Mt 12:31, 32). See Poole on "Luke 12:11"

For the Holy Ghost shall teach you,.... Shall give both words and matter: in the same hour; instantly, immediately:

what ye ought to say; what will be proper to be said, for the honour of Christ, the defence of the Gospel, and the confusion of enemies; See Gill on Matthew 10:20.

For the Holy Ghost shall teach you in the same hour what ye ought to say.
