It is true, of course, that what is an unspeakable gift of God for the lonely individual is easily disregarded and trodden under foot by those who have the gift every day. It is easily forgotten that the fellowship of Christian brethren is a gift of grace, a gift of the Kingdom of God that any day may be taken from us, that the time that still separates us from utter loneliness may be brief indeed. Therefore, let him who until now has had the privilege of living a common Christian life with other Christians praise God’s grace from the bottom of his heart. Let him thank God on his knees and declare: it is grace, nothing but grace, that we are allowed to live in community with Christian brethren.
Dietrich Bonhoeffer, Life Together.
