Ever since the fall in the garden, death has reigned over mankind. The literal keys to the planet had been given to satan and he enforce the rule of death and destruction.
But, Jesus, turned it all on its head, Life is swallowing death.
Yes, the gates of hell; sin, disease and death shall not withstand the ecclesia. We the governmental body of the Kingdom, His called out ones, are to enforce that Kingdom on the earth. Jesus already secured victory over the enemy but He also restored to man all the authority over the earth.
The problem is we do not enforce that authority properly, instead we surrender the rightful place Jesus gave us, to the enemy. We do this because he, satan lies to us and we believe his deceptions! We do not take Jesus at His word and see His miraculous deeds as absolute proof that we are to be like Him in this world. We allow the kingdom of darkness to penetrate the very walls of our kingdom here on earth.
Sharing the good news of salvation. Healing the sick, lifting up the downtrodden, interceding for others, fellowshipping together are the ways we rebuild the breaches in the walls and force back the darkness.
