"And I will give unto thee, keys of the kingdom of heaven, and whatever thou shall bind on earth, shall be bound in heaven, and whatever thou shall loose on earth shall be loosed in heaven. Matt, 16:19

Kingdom keys are the powers that the Lord God has given to the church, but many times church has failed in its duties to put them to work. One of the kingdom keys is " Love"( Mark 12:30 ). It is the key that brings us close to entering into the kingdom of God. The gospel is all about love for God and for people. Another kingdom  key is pure Heart { Matt,5:8 }. How we see God and others depends on the state of our hearts, how pure the heart is. Without this purity of the heart, no man can see or enter the kingdom of God. The third key is mercy ( Matt, 5:7 ). Every believer desires the mercy of God. Don't take vengeance for yourself. Justice and vengeance are in His hands. Furthermore, faith is another kingdom key ( Mark 9:1 ). Faith is build upon the spoken word. The kingdom of God operates in faith and not fear. So, to operate in faith is to operate and live in His kingdom. And the fifty one is His name. His name is above every other thing. And by that name, every power and authority bows. ( Phil,2:9-12 ). Isaiah 22:22-25; Rev, 3:7
