Our faith, our love for God, our holiness, all play themselves out in the context of other people. Church happens when the adopted children of God gather to learn how to be family, to set aside our individual selfishness to learn how to function for the sake of the whole. The mission and life purpose of the whole is to follow the headship of Christ.
"But thanks be to God! He gives us the victory through our Lord Jesus Christ."
1 Corinthians 15:57
