{2} And I say unto you my friends, Be not afraid of them that kill the body, and after that have no more that they can do.

(2) Although hypocrites have princes to execute their cruelty, yet there is no reason why we should be afraid of them, even by the smallest amount that may be, seeing that they can do nothing except that which pleases God, and God does not will anything that may be against the salvation of his elect.

Wesley's Notes

12:4 But I say to you, Fear not - Let not the fear of man make you act the hypocrite, or conceal any thing which I have commissioned you to publish.

Jamieson-Fausset-Brown Bible Commentary

4, 5. I say, &c.-You will say, That may cost us our life. Be it so; but, "My friends, there their power ends." He calls them "my friends" here, not in any loose sense, but, as we think, from the feeling He then had that in this "killing of the body" He and they were going to be affectingly one with each other.

Matthew Henry's Concise Commentary

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.
