The more the merrier?

I have recently seen a few adverts for "Christian Services". One such advert attracted my attention as it was about prayer. Now I am not good at prayer, it is one thing that always slips my mind and so anything that helps, I like.

This, however, was a little strange.

There is a company with whom you sign up using SMS, you then send them a prayer request and they will send the request to lots of other people, lets say 200 other people. In return you have to agree to pray for the next 5 requests that you receive as a text message.

The idea is, I guess, that when you are in a crisis you will almost instantly have a few hundred people praying for you.

This is what Jesus said:

But you, when you pray go into your room, and when you have shut your door, pray to your Father who is on the secret place; and your Father who sees in secret will reward you openly.
Matthew 6:5-6

So we see that our Father sees in secret. Since He not only sees in secret but he knows our needs before we even know them. Matt 6:7 says "...for your Father knows what you need before you ask him."

Yet it is good to pray in groups, to share ones needs with God's people.

Does it some how make a difference if lots of people pray for something? Are you more likely to receive whatever answer you would like if this happens? Is it better to have 10 or 100 or 1000 people pray for you and your needs or is it fine just to pray yourself?
