How does preaching the holy gospel open and close the kingdom of heaven?
Matthew 16:19 – I will give you the keys of the kingdom of heaven; whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.”
John 3:31-36 – The one who comes from above is above all; the one who is from the earth belongs to the earth, and speaks as one from the earth. The one who comes from heaven is above all. He testifies to what he has seen and heard, but no one accepts his testimony. Whoever has accepted it has certified that God is truthful. For the one whom God has sent speaks the words of God, for God gives the Spirit without limit. The Father loves the Son and has placed everything in his hands. Whoever believes in the Son has eternal life, but whoever rejects the Son will not see life, for God’s wrath remains on them.
John 20:21-23 – Again Jesus said, “Peace be with you! As the Father has sent me, I am sending you.” And with that he breathed on them and said, “Receive the Holy Spirit. If you forgive anyone’s sins, their sins are forgiven; if you do not forgive them, they are not forgiven.”
