Trying the spirit is to test the fruit. Many speak "good" and as humans we can not see the hearts of men so The Most High has given us a testing criteria and that is by the testing of the fruit. Ask me to expound and I will. But in short saying test the spirit is vague and most don't understand what that mean and can be deceived but by testing the fruit is simple to understand and all of capable of testing the fruit. What is the fruit? ask and I will let you know.
