This vision teaches future duties for the body of Christ. The wall is brick—not stone. Brick symbolizes that which is man-made. There is “life” beyond the wall (symbolized by the vine). But within the wall (the world) the house (not the house the Lord built) is burning. The believer (symbolized by me) has escaped over the wall into life. But now (in these increasingly dangerous times) others wish to escape the fire to come. We, as believers, are called to help the younger believers over the wall.
