"You yourselves, as living stones, are being built into a spiritual house for a holy priesthood to offer spiritual sacrifices acceptable to God through Jesus Christ." (1 Peter 2:5)
"God builds a palace for Himself in heaven, made of 'living stones'. Where did He get them? Has He brought forth the richest and the purest marble from the fine quarries of Paris? No! Christians, look to 'the hole of the pit where you were dug out of, and to the rock where you were cut from!' You were full of sin. Far from being stones that were white with purity-you were black with defilement, seemingly utterly unfit to be stones in the spiritual temple, which would be the dwelling-place of the Most High God. And yet, He chose you to be trophies of His grace!
Goldsmiths make exquisite jewelry from precious materials; they fashion the bracelet and the ring from gold. But God makes His jewels out of base materials. From the black pebbles of the defiling brooks-He has taken up stones, which He has set in the golden ring of His immutable love, to make them gems to sparkle on His finger forever. He has not selected the best-but apparently the worst of men-to be the monuments of His grace!" (C.H. Spurgeon taken from Grace Gems)
Grace upon grace,
