on the road, while He was explaining

Saturday's post probably warrants some explication. Other than variety for variety's sake, the image came to me during prayer. I titled the piece "Solid Answer". The chosen images are all there for a reason:

* The three squares at the bottom parallel to the one rectangle across the top represents the Trinity, three in one
* The rectangle across the top and the two squares at the bottom are actual cross-sections of a stone wall, signifying a firm foundation
* The third square, bottom left, is a white rock, representing our Rock, with the white representing His holiness
* The three nails have obvious crucifixion significance
* The nails point to the cross, the solid answer
* The center rectangle is a blown-up version of the cross above it, cropped to focus on the intersection of the beams; its resemblance to a crossroads is not coincidental

Next one, yours to interpret.
