In John 15:16, Jesus told His disciples that He had ordained them to bear much fruit, including fruit that would “remain.” Fruit from an apple tree is an apple. Fruit that remains from an apple tree is another apple tree.
In Judges 3:7-11, Caleb’s nephew Othniel (“Lion of God”) was described as having been empowered by Yahweh to be the first of the Judges He gave to Israel to lead them. Othniel’s leadership provided rest to the nation for forty years.
He was prepared in the desert and influenced by Caleb to have powerful and successful purpose in the land of promise. His work was fruit from Caleb’s life that remained.
