Quote #4
and you whose eyes,
Shall behold God, and never taste death's woe. (lines 7-8)
Donne could be talking about two groups here. He could be talking about all good people, who will never taste the sadness of eternal death, or about those good people who happen to be alive on the Day of Judgment, who will never taste earthly death.
Quote #5
for that's as good
As if thou hadst seal'd my pardon, (lines 13-14)
Donne compares divine justice to an official document in the realm of justice on earth. These lines are like the old adage, "Give a man a fish, and you feed him for a day. Teach a man to fish, and you feed him for a lifetime." If God teaches the speaker to repent, it will be like having a pardon for all his past and future sins.
