The preaching of the gospel proclaims Christ’s kingdom has come to us, opening the hearts and minds of those who hear it to the glory of Christ and the good news of his salvation. On the other hand, binding something is to close it. In the context of Christ’s kingdom, it is to close the kingdom to unbelievers.
In Matthew 16:19, Jesus makes the following statement to the apostle Peter:
“I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.”
What was Christ Jesus referring to when he told Peter he would give him the “keys of the kingdom”? What is the meaning of this metaphor that our Lord is using in Matthew 16:19?
The Heidelberg Catechism, question and answer 83, states,
- What are the keys of the kingdom?
- The preaching of the holy gospel and Christian discipline toward repentance. Both of them open the kingdom of heaven to believers and close it to unbelievers.
Jesus Is Referring to the Kingdom of Heaven, His Kingdom That Is Not of This World
