Jesus gave a sterling promise regarding the Kingdom of God.
"And I also say to you that you are Peter, and on this rock I will build My church, and the gates of Hades shall not prevail against it" (Matthew 16:18).
Jesus promises to build his church. Jesus uses a play on words saying, “You are Peter (rock), and on this rock (stone), I will build my church.” Remember, that according to Daniel 2, the Kingdom of God begins with a stone. Again, we also encounter the indestructible nature of the Kingdom of God. Not even the gates of Hades, that is death, will prevail against it. The Kingdom of God will triumph over all of its enemies.
Building the Kingdom
How is Jesus building his Kingdom? "
And Jesus came and spoke to them, saying, 'All authority has been given to Me in heaven and on earth. Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of the age. Amen." (Matthew 28:18-20).
Jesus ascended to the right hand of God and is ruling and reigning over the universe through the church. The church’s mandate is to make disciples of all the nations. Become a mountain. Grow into a tree. Leaven the entire loaf.
