That he maybe stubborn and does not want to comply
In the lines: "life's but a walking shadow, a poor player that struts and frets his hour upon the stage", Macbeth is expressing that life lacks substance and he is also comparing it to the life of an actor who is performing and all of a sudden he is no longer doing so.
In the lines: "it is a tale/told by an idiot, full of sound and fury signifying nothing", Macbeth is comparing life to a story told by someone who lacks intelligence; therefore, it is sort of meaningless.
Answer:We kneel, how weak; we rise, how full of power!
Why, therefore, should we do ourselves this wrong,
Or others - that we are not always strong,
That we are ever overborne with care,
That we should ever weak or heartless be,
Anxious or troubled, when with us is prayer,
And joy and strength and courage are with Thee?
