John 17: 20-21

20 “My prayer is not for them alone. I pray also for those who will believe in me through their message,

21 that all of them may be one, Father, just as you are in me and I am in you. May they also be in us so that the world may believe that you have sent me.

The union of Christians is a very strong binding between humans and our Lord. We pray for our beloved family, our friends, other persons we know and for the whole humanity. Our Lord shows us this in His example. He is the one who connects us with His father in love – he gave his life for us.
