Broken Toys.
Some little children were playing with a toy Noah's ark, and filled the bathtub to represent the flood. Then they thought they would go further and represent the sacrifice after the flood. Making an altar out of the soap dish and some pieces of wood, they tried to decide which animal should be offered up. Finally they selected a sheep with two broken legs.
We need not laugh at those children, for they were only too faithful a copy of their elders. We see that God's cause requires sacrifices, if it is to win the world. We know that Christians are the only people to make those sacrifices. Then we look around for some toy which we have spoiled, or of which we are tired. That will answer famously!
Some day, when we look back from heaven at our earthly treasures, how we shall wish that we had given them all to Jesus while we could!
