Mark 4:30, “Why are you afraid? Do you still have no faith?”
When put in a syllogism it shows Jesus Christ is stating premises 2 and 3 of a Modus Tollens.
This little syllogism shows the positive first (faith) and the negative in the consequent (fear). This is a statement about reality about stating a positive in antecedent and denying the contradiction as a necessary consequence. Very basic, but very important foundations for having a correct understanding of reality.
Thus, faith and fear do not belong together. Any teaching that tries to put these together is false. We also see the moral lesson from Jesus. Jesus expects a return on His investment. He has deposited faith into His children and expects a return of faith being produced and not the contradiction of fear.
