And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it. And I will give unto thee the keys of the kingdom of heaven:and whatsoever thou shalt bind on earth shall be bound in heaven:and whatsoever thou shalt loose on earth shall be loosed in heaven. Matthew 16:18-19.
One of the concept that come clear from the covenant is heaven on earth. The distinction includes definition of angelic and demonic operations. One or the other is always in operation, you need to take a stand. A stand with one or against the other; no neutral positions.
The covenant is the gate keeper, the church is the carrier. Christ is the head of the church, his body has many parts. The head is the defender of the body with the keys to the gates of hell. Angelic forces are deployed and on duty for your defence. He that holds the key to the gates secures the city and your life.
Your saviour is also your keeper; that is the covenant blessing.

“That in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which is upon the sea shore; and thy seed shall possess the gate of his enemies;” Genesis 22:17.

At the gates, evil has no access; the key is given to the Church. Those that take the church for granted are grounded by the gates of hell. The keys give access to the safe place; Zion, city of our God. No devil nor evil can access your position in the secret place of the most high. Those that take for granted this safe place open themselves to the enemy.. Zion or the church is the place where offences end and the shield is sure.
Innumerable Angelic activity abound around the saints in Zion.  Heaven meets the earth in Zion and the covenant is in full force.
If God is doing anything on the earth, it starts from Zion. That is the secret place, the shadow of the most high; Zion, city of our God. Check you location, if you’re not in Zion, relocate fast to the city of refuge.
Welcome to Zion.

“But ye are come unto mount Sion, and unto the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels, To the general assembly and church of the firstborn, which are written in heaven, and to God the Judge of all, and to the spirits of just men made perfect, And to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel.”Hebrews 12:22-24.
