The true strength and character of a tree is the fruit it bears. By your words, your actions, and the fulfillment of the promises you make, people can determine if you are a good tree or a bad tree. So if your fruit is good then you have to be good. So when people taste or test and see who you truly are do they like what they see or what they learn of you?
Luke 3:8a
8 Do those things that prove that you have turned to God and have changed the way you think and act.
John 15:8
8 When you produce much fruit, you are my true disciples. This brings great glory to my Father.
