“Launch out into the deep,” Christ spake of old

“Launch out into the deep,” Christ spake of old
To Peter: and he launched into the deep;
Strengthened should tempest wake which lay asleep,
Strengthened to suffer heat or suffer cold.
Thus, in Christ’s Prescience: patient to behold
A fall, a rise, a scaling Heaven’s high steep;
Prescience of Love, which deigned to overleap
The mire of human errors manifold.
