But otherwise Jesus’ claim retains its tactfulness. Jesus was clear and yet always discreet. He was clear and yet always reticent. It is from this very implicit, often hidden, often concealed, and yet all-penetrating Christology that a great power emerges. Fundamentally that power is much greater than if Jesus had spoken in the language of the Fourth Gospel, where everything is direct and immediate to the point of provocation. There Jesus says “whoever has seen me has seen the Father” (John 14:9), or still more clearly, “The Father and I are one” (John 10:30). In the course of the first century this explicit Christology became necessary, and it was altogether appropriate and accurate. But it was not the language of Jesus.
A Successful Break-In
The power of Jesus’ language lies precisely in the fact that it only points the way. One last text can show us that. It is in Luke 12:39 and reads in some translations “if the owner of the house knew at what hour the thief was coming, he would prevent his house from being broken into.” This image, or similitude, played an extraordinary role in the early church. It admonishes to watchfulness. It was intended to say: we know neither the day nor the hour in which Christ will appear in glory. He will come as suddenly and unexpectedly as a thief in the night. Therefore be ready at all times! Keep awake!
Naturally, Christ is not portrayed as a burglar here. The point of comparison is only the suddenness and unpredictability of his return. So it is not that Christ is a thief but rather that he will come as unexpectedly
In that case this similitude belongs within a series of texts that speak in similar fashion of the reign of God as having already come, for example: “If it is by the finger of God that I cast out the demons, then the kingdom of God has come to you” (Luke 11:20). The following metaphor also presumes the having-already-come of the reign of God. The background here is again Jesus’ exorcisms of demons: “No one can enter a strong man’s house and plunder his property without first tying up the strong man; then indeed the house can be plundered” (Mark 3:27). This image too does not speak of coming events; against the background of Luke 11:20 it means to say that everything is already happening. Jesus is already in the “house of the strong man,” that is, he has pushed his way into the world ruled by demons.23
The Satan is already bound, the power of the demons already broken.Mark 3:27 in particular is especially close to the text we began with, Luke 12:39, because there too a “house” is invaded. Thus the interpretation of Luke 12:39 I have presented here fits thoroughly within Jesus’ bold way of speaking, one that is not frightened of daring images. Similarly bold and “violent” is the so-called violence saying: “The prophets and the law [were in effect] until John. From then on the kingdom of heaven has broken its path with violence, and the violent take it by force” (cf. Matt 11:13, 12 // Luke 16:16). Against this whole background the similitude of the thief who breaks into a house during the night reveals an excellent sense. Jesus could, in the sense of the thing, have spoken as follows:
To what shall I compare the reign of God? What image shall I use for it—for you doubters who think the reign of God is still far in the future? But it has already come. Its coming is like a break-in that could not be prevented. If the owner of the house had known at what hour the thief was coming he would, of course, have kept watch. But he did not know. And so the thief broke into his house.
In this similitude Jesus does not seem to be speaking about himself at all. As so often, he talks of the coming of the reign of God. And yet he speaks in the same similitude about his own activity.
