Trees are consistent in the kind of fruit they produce. Apple trees produce apples; pear trees produce pears, etc. Healthy trees will always produce healthy fruit. Trees that are diseased and dead will produce unhealthy fruit or no fruit at all. In the same way, followers of Christ should bear spiritual fruit in their faith. If we are connected and rooted in Jesus Christ, the Holy Spirit will produce the Fruit of the Spirit in us. The world will know us by our fruits.
