Impotent
Lacking in power, as to act effectively; helpless.

The greatest danger facing congregations today is not from without, but from within. Problems within the body pose a much greater danger than any outside force. Here are six ways a congregation can become ineffective and impotent, with the light of the Gospel no longer shining and the love of Jesus Christ no longer present. The building may still be standing. The name may still appear on the sign. And members may still congregate.

* When the church becomes polluted by worldliness.
* When the church is busy with other things than His.
* When churches seek to attract people by "glitter" rather than the Gospel.
* When "thus says the Lord" is considered radical and narrow-minded.
* When members fuss, fight and splinter the body over personal views.
* When members do not maintain the spirit and attitude of Jesus Christ.

I, therefore, the prisoner of the Lord, entreat you to walk in a manner worthy of the calling with which you have been called, with all humility and gentleness, with patience, showing forbearance to one another in love, being diligent to
preserve the unity of the Spirit in the bond of peace.
Ephesians 4:1-3

The following quote sends a warning to churches:
But I have this against you, [Ephesian church] that you have left your first love. Remember therefore from where you have fallen, and repent and do the deeds
you did at first; or else I am coming to you, and will remove your
lampstand out of its place--unless you repent.
Revelation 2:4-5
