Jesus Himself said that a good tree bears good fruit and that we would meet false prophets by their fruit. The fruits are visible, you know that the fruits of an apple tree are in sight, in the same way the actions of people, whether good or bad, are in the light of day.
But the Bible not only tells us about the bad actions of false prophets, there are also a series of fruits that tells us that those who live in the Spirit must possess them:
22 But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,
23 Meekness, temperance: against such there is no law.
Many times these verses are left behind when we are going to refer to spirituality, and it should not be so, because they are the very essence of a man and a woman who actually leads a healthy and admirable spiritual life.
Let us be careful not to fall into the same error as the Corinthians, who thought that by having an abundance of spiritual gifts they were really spiritual.
The gifts are a powerful gift from God, but the fruits are the full and pure demonstration that we really are children of God, that we are different. Therefore, brothers, let us try to show each one of those fruits.
