Jesus and the apostles are the only examples that God gave us
of how to live out an effective ministry.
It was not dependent on techniques, programs, or traditions
He gave us an impossible standard and it is supposed to be.
It humbles us and to make us know that in ourselves dwells no good thing Ro 7:18, but with God all things are possible
So simple, so impossible 2Co 12:9
There may be more aspects of this, but what other foundation can there be?
The entire way of ministry can be summed up in this verse
Mt 4:4 But he answered and said, It is written, Man shall not live by bread alone, but by every word spoken that proceedeth currently out of the mouth of God.
All other verses are but proof and examples that this is the key verse.
