John 10:27

Observe how in renouncing He exciteth them to follow Him. "Ye hear Me not," He saith, "for neither are ye sheep, but they who follow, these are of the flock." This He said, that they might strive to become sheep. Then by mentioning what they should obtain, He maketh these men jealous, so as to rouse them, and cause them to desire such things.

(Tract. xlviii. 5, 6) This is the pasture of which He spoke before: And shall find pasture. Eternal life is called a goodly pasture: the grass thereof withereth not, all is spread with verdure. But these cavillers thought only of this present life. And they shall not perish eternally; as if to say, Ye shall perish eternally, because ye are not of My sheep.

"My sheep hear my voice, and I know them, and they follow me: and I give unto them eternal life." This is the pasture. "I will give," He says, "unto them," unto my sheep, "eternal life." Ye are on the search for calumnies, just because your only thoughts are of the life that is present.

i. e. Obey My precepts from the heart. And I know them, and they follow Me, here by walking in gentleness and innocence, hereafter by entering the joys of eternal life: And I give unto them eternal life.

After He had said, Ye are not of My sheep, He exhorts them to become such: My sheep hear My voice.
