While wondering if he should really kill Duncan, Macbeth acknowledges, “We’d jump the life to come,”
a reference to the afterlife, which Christians believed would be granted to those who honoured God. Macbeth knows committing murder will sacrifice his life in Heaven, making him fully mortal and abandoned by God. The threat of this is enough to make Macbeth reconsider his plan, showing the power religion and belief had over people at the time. Shakespeare suggests Macbeth should have listened to his conscience and faith rather than to his wife.
