4. And when Jesus saw their thoughts He now gives a proof of his Divinity in bringing to light their secret thoughts: for who knoweth the things of a man but the spirit of man which is in him? (1 Corinthians 2:11.) And so Mark adds, that Jesus knew by his Spirit: which means, that what was concealed in their hearts could not be perceived by man, but that Christ by his Divine Spirit knew it thoroughly. Why do you think evil? This does not imply that it gave them pain to see a mortal man assuming what God claims as his own prerogative, but that they proudly and wickedly rejected God, who was openly manifested to them.
