God has chosen to put the greatest treasure of all, not inside of gun safes, but inside clay jars, or earthenware vessels; not inside of strength, but inside brokenness and weakness. It's intentional. There's purpose behind our weakness. It's so the treasure is seen all the more clearly.
What construction company sets out to build a building without first giving a bid? What king goes to war without first counting his troops? Jesus uses those to parables to say you shouldn’t be so fast to just raise your hand to follow him without first considering what it will mean.
