This is the picture story. One builder starts to build a house. First, he puts cement down on the ground for the building to stand on. That cement is called the foundation. Then other builders build the house on that cement foundation. This story is a picture of you getting into God’s family. God was good to me and gave me the power to work for him. I told you about Jesus, and it is like I put down a good foundation for you at that time. And now other Christian workers are teaching you more about Jesus. They are like the builders that build on that foundation. They have to do it properly. Jesus is the only strong foundation. Nobody can put down any other foundation for God’s family.
