Another Bonhoeffer quote, which one might quibble with a bit in its expression, but the sentiment certainly demands an amen.
“Bear one another’s burdens, and in this way you will fulfill the law of Christ” (Gal. 6:2). Thus the law of Christ is a law of forbearance. Forbearance means enduring and suffering. The other person is a burden to the Christian, in fact for the Christian most of all. The other person never becomes a burden at all for the pagans. They simply stay clear of every burden the other person may create for them. However, Christians must bear the burden of one another. Only as a burden is the other really a brother or sister and not just an object to be controlled.
