Jesus initiated a relationship with Zaccheus. Since he called him by name He evidently knew about him, though Zaccheus had obviously not seen Jesus formerly. Jesus not only wanted to talk with him but to stay in his house. Jesus spoke as though He felt compelled to do this, as is clear from the recurrence of one of Luke"s favorite words, "must" (Gr. dei, cf. Luke 4:43; et al.). "Today" further stresses urgency and the fulfillment of God"s plan (cf. Luke 2:11; Luke 4:21; Luke 19:9). [1] This attitude was typical of Jesus who sought out lost people. Zaccheus gladly and obediently responded to Jesus" offer. [source][source][source]
