How does WT in the OP.. get away with saying "in imitation of Jesus Christ, prefer to devote their time and financial resources to announcing the “good news of [God’s] kingdom."
In their eyes, the healing and resurrections that Jesus performed were just to prove that he could do it; to foreshadow what he would do as King. So the Society can safely ignore that sappy stuff and focus only on his ministry as a preacher.
