The Keys of the Kingdom

Jesus gave Peter the keys to the kingdom of heaven. A key opens doors or locks doors.

I will give you the keys of the kingdom of heaven; … Mt 16:19 NIV

When Peter preached the good news of Jesus on the first day of Pentecost, he opened the door for 2,000 Jews from different nations to enter God's kingdom of heaven.  

... whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.” Mt 16:19 NIV

When Peter was anointed by the Holy Spirit and proclaimed God's truth and grace in his preaching, the power of unbelief was bound and the grace of salvation was loosed.

You could also visualise it differently.
The door to hell was closed and the door to eternal life was opened.

But was it only Peter's sermon that opened the door of faith?

“ ‘In the last days, God says, I will pour out my Spirit on all people. Your sons and daughters will prophesy, your young men will see visions, your old men will dream dreams. Ac 2:17 NIV

120 disciples, men and women, were dramatically filled with the Holy Spirit. They uttered prophetic words from the Holy Spirit and they spoke these words in languages they had never learnt. These languages were also understood by the listeners from different nations.

God gives the keys of the kingdom of heaven to all disciples in all generations. If you let yourself be led by the Holy Spirit, he will give you words that will touch people.

God wants to give you words of love, words of grace and also words of truth.
