Josh can do lots of things his dog cannot do. The kind of life God has put into Josh gives him power to live a better life than Spot can. He can learn to read, use a knife and a fork, and a whole lot of things a dog cannot do. It is better than plant life. It is better than animal life and it is better than human life.
Many people are alive because they have human life.
But they are also dead, because they do not have God's life living in them. And the Bible says that unless you have God's Son, Jesus, you cannot have God's life. But if you have Jesus, you also have THE LIFE OF GOD living in you. We believe people when they say something is true. But what God says is more important.
