It is written in Romans 9:21-24, that we are as clay in the Potter’s hands. "Hath not the potter power over the clay, of the same lump to make one vessel unto honor, and another unto dishonor? What if God, willing to shew His wrath, and to make His power known, endured with much longsuffering the vessels of wrath fitted to destruction: And that He might make known the riches of His glory on the vessels of mercy, which He had afore prepared unto glory, Even us, whom He hath called, not of the Jews only, but also of the Gentiles?"

A potter can fashion a vessel suited for mundane use, such as a spittoon, or he can make a vessel so exquisitely beautiful that it is worthy to be displayed in a king’s palace. It is solely the will of the potter to decide what sort of vessel he would make. This is even more true with our sovereign God. He has the right, and actually exercises the right, to fashion every son and daughter of Adam into whatever kind of vessel He chooses. If you and I are glorious vessels of mercy, made beautiful through the comeliness of our Lord Christ Jesus, it is not for us to glory in ourselves.
