16我们对基督的经历，需要从二度进到三度，从“平面”进到“立方体”。……在会幕和圣殿里的至圣所都是立方体。在会幕和圣殿中这个立方体的量度分别是十肘和二十肘。新耶路撒冷将是一个永远的立方体，长宽高各是一万二千斯泰底亚。今天召会生活也必须是“立方体”。……我们在召会中对基督的经历也必须是“立体的”，是三度的……。当我们成为一立方体时，我们就既不倒也不破。基督是宇宙的立方体，召会生活今天也是“立方体”，不是“线”，甚至也不是“地毯”。……当我们对基督有来、去、上、下的经历，至终我们就会有扎实的“立方体”（以弗所书生命读经，三四八至三四九页）。
16In our experience of Christ, we should go on from the two dimensions to three, from a “square” to a “cube.”…Both in the tabernacle and in the temple, the Holy of Holies was a cube. The dimensions of this cube in the tabernacle and temple respectively were ten cubits and twenty cubits. The New Jerusalem will be an eternal cube, twelve thousand stadia in three dimensions. The church life today must also be a “cube.”…Our experience of Christ in the church must be “cubical,” three-dimensional… When we become a cube, we cannot fall, and we cannot be broken. Christ is the universal cube, and the church life today is also a “cube,” not a “line” or even a “carpet.”…As we go back and forth and up and down in our experience of Christ, we eventually have a solid “cube.” (Life-study of Ephesians, pp. 276-277)
