Can "faith in Jesus" be separated from "faith of Jesus"? Very often, we have seen in the history and today``s life of the church a Jesus who is "divorced" from his message and ministry of the "kingdom of God." Christians often confess a Christ who does not resemble Jesus; and Jesus, preached in isolation from his message and ministry of the kingdom, usually develops into a cult of Jesus. Tracing and criticizing the history of the scholarly quest for the "historical Jesus," the author first argues that the "Jesus of history" and the "Christ of faith" need not to be separated, nor should be confused, but maintain a dialectical and integral relationship for the authenticity of Christian faith. Also analyzing the result of contemporary research of the historical Jesus, the author proposes that the "wisdom tradition," which has long been forgotten in the history of Christian church, should be reinstated and given a due status in Christological reflections so that Christians may be guided to discover God``s saving grace and redeeming power in the "daily," the "trivial," and what has been regarded as the "womanly." Finally exegeting Jesus`` parable of the "mustard seed" in Mark 4:30-32 (also in Matthew 13:31-32, Luke 13:18-19, and Thomas 20:1-4) in light of the traditional image of the "kingdom" in Ezekiel 17:22-23, the author recaptures the "shock" of Jesus`` message of the "kingdom of God" in societies now and then. Campus ministry, according to the author, is a joyful and challenging mission to invite students to come to the stage of a Christian faith in which "faith in Jesus" and "Jesus`` faith in the kingdom of God" are integrated and united.
