Family relationships are, or should be, the strong girders around which society is built.  In a way, gospel-friends are even more significant because they enable Christ’s church to be built.  They are not just acquaintances; they are blood relatives in a dynasty that will never die!  The blood belongs to Jesus Christ, whose sacrifice brought us into His family, making us brothers and sisters with Him (Hebrews 2:11).  No wonder that Paul was thankful for the believers in Philippi. His house arrest (probably in Rome) was made easier when he remembered the love of his spiritual family.
