WT book ' jesus The Way The Truth and Life chapt 87 ( discusses Luke 16 )
"Only Jehovah God and his Son can receive someone into the heavenly Kingdom or the Paradise on earth under that Kingdom. We should diligently cultivate friendship with them by using what material riches we have in supporting Kingdom interests. Our everlasting future will thus be assured when gold, silver, and other material riches fail or perish."
