Intercession or intercessory prayer is offered to God as believers stand in gap for other people. Christians must not be obsessed with our needs only, but we must intercede for others and ask God to meet their needs also.
The Bible reference
“Again I say unto you, that if two of you shall agree on earth as touching anything that they shall ask, it shall be done for them of my Father which is in heaven. For where two or three are gathered together in my name, there am I in the midst of them.”
(Matthew 18:19- 20 KJV)
