Often times, I think that when we pray something like this, we say our prayer and think our responsibility ends there. Right after Jesus commanded his disciples to pray for the Lord to send out workers for the harvest, do you know what happened next? Jesus sent out the twelve into the towns of Israel in order to prepare the way. They were to preach and to heal, going about with the full authority that Jesus gave them.
When we pray something, especially something that we know is in line with the will of God, we better be prepared to be the answer to that prayer. If we pray for God to provide the homeless with shelter on a cold winter night, we better be prepared to find some way to provide that shelter for them ourselves if they show up on our doorstep. If we pray for the hungry to be filled, we better be prepared to give out food. When we pray for God's will to be done, we ought to be prepared to be the instruments of God in fulfilling that very prayer.
