Ephesians 2:19 “Now, therefore, you are no longer foreigners and strangers, but members of the household (family) of God”
We are made for His family. There are so many verses on one-another (love one another, encourage one another, etc) in the New Testament, God teaches us that we can’t grow in isolation.
Loving is shown by giving and serving. God gives every member a part in His body to serve one another, to help one another to grow.
