Claude McKay - Baptism

Into the furnace let me go alone;
Stay you without in terror of the heat.
I will go naked in--for thus ''tis sweet--
Into the weird depths of the hottest zone.
I will not quiver in the frailest bone,
You will not note a flicker of defeat;
My heart shall tremble not its fate to meet,
My mouth give utterance to any moan.
The yawning oven spits forth fiery spears;
Red aspish tongues shout wordlessly my name.
Desire destroys, consumes my mortal fears,
Transforming me into a shape of flame.
I will come out, back to your world of tears,
A stronger soul within a finer frame.
