The fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control... Galations 5:22-23
If you are looking at two trees that are bearing fruit, an apple tree and an orange tree, can you tell just by looking at them which one is the apple tree and which is the orange tree? Of course you can, because you know what apples and oranges look like. The evidence that a tree is an apple tree is that the fruit growing there are apples. The evidence that a tree is an orange tree is that the fruit growing on it are oranges. In the same way, if you are a Christian, people should be able to look at your life and recognize that you are a believer because of the fruit your life bears -- love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control. Not too long ago, someone described me as a "happy person". Hopefully, what they thought was happiness, was actually the joy that can only come from being in Christ. Being happy is dependent on circumstances around us, but joy is something God-given and it doesn't go away when life throws us difficult situations. What kind of fruit does your life bear?
Each tree is recognized by its own fruit. People do not pick figs from thornbushes, or grapes from briers. Luke 6:44...for out of the overflow of his heart his mouth speaks. Luke 6:45b
