everyman: morality play

which phrase in this excerpt from the play everyman refers to god's judgment of people's souls after their death?

messenger: . .

ye think sin in the beginning full sweet,

which in( the end) causeth thy soul to weep,

when the body lieth in clay.

here shall you see how fellowship and jollity,

both strength, pleasure, and beauty,

will fade from thee as flower in may.

for ye shall hear, how our heavenly king

calleth everyman to a (general reckoning):

give audience, and hear what he doth say.

god: i perceive here in my majesty,

how that all the creatures be to me unkind,

living without dread in worldly prosperity:

of (ghostly sight) the people be so blind,

drowned in sin, they know me not for their god;

in worldly riches is all their mind,

they fear not( my righteousness), the sharp rod;

(my law that i shewed), when i for them die

hopefully this !
