Be strong in Me;
and you, too, Andrew;
just as you were the first to find Me, you were found by me;
so find the one who has wandered;
Do not forget your first skill;
from it I shall educate you for this new art.
Formerly, naked into the deep sea, now naked into life;
Formerly, hunting with a fishing-rod, now taught to fish with the cross;
Formerly, you used a worm as bait;
now I order you to hunt with My flesh.
I alone know what is in the heart.
