On healings and exorcisms in our world today, T. Desmond Alexander writes:
…It is possible for Jesus’ followers also to experience in the present something of the eschatological age in terms of healings and exorcisms. However, this will always be less than what awaits us. God may heal, here and now, but not on every occasion. There may be occasions, here and now, when evil powers are defeated, but not always. This should not surprise us. The present evil age will eventually give way to the next. If we all received from God complete holiness and wholeness now, there would be no need for the new earth. As it is, however, we live on an earth presently controlled by the evil one. Only when Satan is finally defeated shall we know life as God intended it (From Eden to the New Jerusalem,155: emphasis added).
Presently we find ourselves living in the tension of the already-but-not-yet. We are now experiencing the kingdom of God as believers, but the kingdom awaits its full consummation. We await the return of the king of kings, who will bring with him the new heavens and new earth we long for. But as Alexander states, right now we only “have a glimpse of what the coming age will be like.”
