How Can Michael Hale Produce Good Fruit from a Bad Foundation (Vine)?

I heard a pastor say at Sunday morning service in regards to The Global School of Supernatural Ministry that you "need to look at what comes out of it" and then described the results as "good fruit from a bad foundation." To clarify and to make my point fruit cannot come from foundations only from roots or trees of course. Matthew 7:15-20 says good fruit can only come from healthy trees. So anything appearing to be good fruit from a bad foundation (tree) will wither and rot to the ground.

Matthew 7:15 also begins by stating that false profits coming in sheep's clothing are but ravenous wolves. So does it then make sense that a so called good fruit from a bad foundation (tree) is representative of the sheep and the rotting fruit the same as wolves clothing?

Micheal Hale and his Kingdom Ministries, a satellite of the Global School, as long as he uses false teachers Randy Clark or Bill Johnson in his videos or teachings, can no way bear good fruit. Johnson and Clark believe and have written that Christ gave up his divinity while on earth. This is a cornerstone of their teachings on how we should be raising the dead and performing miracles. THEY DENY THE TRINITY. Even if letting go of the trinity for the thirty years Christ was on earth it is still a denial. The most important event in the history of man was Christ's arrival on earth in the flesh.

Matthew 7:15-20 ESV

"Beware of false prophets, who come to you in sheep's clothing but inwardly are ravenous wolves. You will recognize them by their fruits. Are grapes gathered from thorn bushes, or figs from thistles? So, every healthy tree bears good fruit, but the diseased tree bears bad fruit. A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit.
