Jesus said that a good tree bears good fruit and a bad tree produces bad fruit.
What this means is that a good leader produces outcomes that delight and satisfy and nourish and sustain you.
While a bad leader produces outcomes that depress and frustrate and injure and threaten you.
He says grapes are not gathered from thorn bushes nor figs from thistles.
This means you should not seek help from somebody who does not have the desire to help you.
Neither should you seek insight or knowledge from somebody who doesn’t have the moral, spiritual or experiential qualifications to help you.
A person capable of helping you but not interested in helping you will cause you harm if you are too aggressive about calling upon them for help.
A person interested in helping you but not capable of helping you will cause you anger and rage if you give them chances to disappoint and hurt you by depending on them.
Better not to accept help at all and not seek out help, than to inquire for aid from the wrong person.
