Nature in Scripture: Tree of good & evil, Fig tree, Cedars of Lebanon, Oaks of righteousness (Isaiah 61:3), Fruit bearing (John 15:8).We are to bear good fruit, we represent God's glory when we do this. We are a part of a great symphony of praise before the Lord. Our duties in a nutshell- Heb 10: 19-25 = draw near to God with a true heart. Also, like to young walnut tree bares the same fruit as a seasoned tree, all can be used, young and old and bear the fruit of the Lord.
