How to Relate to the Eternal Family

"Man-wife-children families are temporary blessings for this age. In the age to come, they will not exist (Matthew 22:23-30). But the church will exist as a family forever. This has profound implications...." John Piper This Momentary Marriage

What? This jumped out at me! I had to look up the verses. What does that mean about how we develop relationships that are in the church?

Families are temporary, earthly blessings. We spend a lot of time growing our family, training, eating, teaching, bathing, loving, etc... There is a lot of scripture to back that up as okay. It's a good thing to take care of your physical family.

But what does Matthew 22:30 actually say?

 For in the resurrection they neither marry nor are given in marriage, but are like angels in heaven. Matthew 22:30

Then, referring to this verse, what about those families that aren't blood related, those in the body of Christ, but weren't born into our own homes?  How are we to relate to them? These are just a few ideas:

• Philemon 1:22 At the same time, prepare a guest room for me, for I am hoping that through your prayers I will be graciously given to you.
• I Thessalonians 1:2 We give thanks to God always for all of you, constantly mentioning you in our prayers.
•  I Peter 4:9 Show hospitality to one another without grumbling. 
• Romans 12:13 Contribute to the needs of the saints and seek to show hospitality.
• I Timothy 5:10 And having a reputation for good works: if she has brought up children, has shown hospitality, has washed the feet of the saints, has cared for the afflicted, and has devoted herself to every good work.
• Acts 2:42 And they devoted themselves to the apostles' teaching and the fellowship, to the breaking of bread and the prayers.
• Acts 2:45 And they were selling their possessions and belongings and distributing the proceeds to all as had need.
• Titus 2:4 And so train the young women to love their husbands and children.
