1 Corinthians 12 : 26 And whether one member suffer, all the members suffer with it; or one member be honoured, all the members rejoice with it. 27 Now ye are the body of Christ, and members in particular.

Paul makes a good point here that when there is suffering or injury to any member of a body of Christ, then  the whole body suffers. We also know that when someone is blessed or has had a miracle or prayer answered in their life thew whole body rejoices with them. We should always strive to know the needs of the body of Christ we are in and help when needed and rejoice when needs are met. Prayer and praise are what makes this work according to the will of God. Sometimes the only thing we can do is pray for the needs of someone to met, but we can always praise God when he blesses people and us.
