{For we preach not ourselves} (ou gar heautous k(8872)ussomen).
Surely as poor and disgusting a topic as a preacher can find.
{But Christ Jesus as Lord} (alla Christon I(8873)oun Kurion).
Kurion is predicate accusative in apposition. {As your servants
for Jesus' sake} (doulous hum(936e) dia I(8873)oun). Your bond-slave
for the sake of Jesus. This is the sufficient reason for any
preacher's sacrifice, "for Jesus' sake."
