Matthew 16:19

19 I will give you the keys to the kingdom of heaven. You will tell people here on earth what is right for them to do. And you will tell them what is not right for them to do. God in heaven will give you this authority. He will agree with what you say.’

16:18Jesus used a house that someone builds on a rock as a picture. The house is like the church. The things that Peter would teach are like the stones under the house. One day soon, Jesus would go back to live in heaven again. Then Peter would be a leader of the disciples to teach the people the true things about God. The people who obeyed Jesus' words would be called the church.
