Direct Answer
The image shows a God who keeps working on people who do not yet fit, and who removes what must go so they can return. His patience includes the painful work of cutting away sin.
Support from the Message
- The round stone "cannot become square unless it is trimmed and loses part of itself." - God has to trim away and chisel the stone to get rid of sin so that it can be brought back into the tower. - Tom Kruger says plainly that "repentance is that trimming" and that it brings people back to be a part of the church. - All of the stones had the chance to repent, and God is still working on them and chiseling them, though not all reach the tower.

Where have you felt God's trimming as a loss? How might seeing that loss as his work of bringing you back change the way you respond to it?
