A devotee should not try to question or understand everything about the Lord's plan, but it is the duty and responsibility of the devotee to simply be obedient to the Lord's plan. Whatever the Lord asks of me, then one should be prepared to perform it. In this way the surrendered soul who is always obedient to the will of the Lord will be instrumental in executing the Lord's plan which ultimately is Krishna's desire and will manifest anyway.
