Technically, if two agree on anything, it shall be done in heaven. This video explains when the Lord does things for us in heaven:
Matthew 18:19 King James Version (KJV)
19 Again I say unto you, That if two of you shall agree on earth as touching any thing that they shall ask, it shall be done for them of my Father which is in heaven.
This needs to be balanced against this verse:
James 4:3King James Version (KJV)
3 Ye ask, and receive not, because ye ask amiss, that ye may consume it upon your lusts.
If we are guided by the Holy Spirit and request things that are consistent with the will of God only then it shall be done for them. For example, asking for Holy Spirit fire, warrior angels to wage warfare, binding and rebuking demons, commanding the body to heal, asking for gifts of the Holy Spirit etc…
