We are here because of the gift of God. We give the gift of life to others by our own willingness to suffer on their behalf . Christian love is a free gift or its not Christian love.
The ultimate purpose for the entire existence of the Church is to glorify God, to glorify God.
The willingness to serve in the model of Jesus, it has to be free and it has to be understood that one is doing it because this is what Jesus called us to by the gift of faith, to serve, but to serve without any desire for reciprocation.
