There are many gates mentioned in the Bible. There are gates mentioned that are great and high; the gates of the heavenly Jerusalem. The gates mentioned in the Old Testament were where the city leaders would frequent; Lot sat at the gates of Sodom; he was a influential man with a good reputation in that city. The Bible mentions gates of death; and the gates of hell and the grave.
In this physical body we cannot perceive these gates wih our natural eyes. They are spiritual in nature. I remember sermons by Brother David Wilkerson about the forces that have influence over New York City. Gates of finance control that city. Washington DC the gates are powerful in the influence, position and politics. San Francisco the influence of money, sex and influence have powerful influence.
In the areas in which we live there are also principalities and powers in control that we battle on a daily basis. But no matter the influence, they all have to bow in the Presence of God. The Presence of God in us causes great difficulty for these spiritual powers. This is where our battle lies. We have been given great power in the pulling down of strongholds. We have this power through prayer.
Psalm 24:7-10 ~ " Lift up your heads, O ye gates; and be ye lift up. ye everlasting doors; and the King of Glory shall come in. Who is the King of Glory? The LORD strong and mighty, the LORD mighty in battle. "
" Lift up your heads, O ye gates; even lift them up, ye everlasting doors;and the King of Glory shall come in. Who is the King of glory? The LORD of Hosts (armies) He is the King of Glory!"
At the Name of Christ every knee shall bow, every tongue will confess, that He is LORD of all!
