In evaluating ministers and ministries, more attention should be given to the fruit that is being produced. Failure to do this could lead someone to reject and even discredit a minister who simply makes a mistake or is wrong in one area. Every minister has shortcomings, just as every other member of the Body of Christ does. But that doesn't mean his ministry is bad. Look at the fruit.
Fruit is the true test of ministers and ministries. If people are being saved, if lives are being changed, there is good fruit. Even though the minister may say something bad and make mistakes, the fruit is good.
Therefore, you can say that the tree is good. When a person says all of the right things and may seem sincere, but you see the lives of people around them shattered and torn, and in confusion and distress, then the fruit is bad. You can judge the effectiveness of a person by the fruit that they are producing in their life. In ministry you can judge the effectiveness of a minister by the fruit that his ministry is producing.
