How many souls advanced unto God, entered the shadow of the
Word of God and became celebrated in the world, as Judas Iscariot. Then, when
the tests became severe and trials great, their feet turned from the path;
turned from confession to denial; changed from love and affection to severe
enmity. Then the power of tests, whereby the foundations shake, were
manifested.
