What is a piece of technology you are convinced that will exist in 20 years?  The android and I phones will become a whole lot more advanced than usual.  Whereas there would be a Holy Bible that will become more advanced than usual as well. Apps would become more advanced as well in the future.  If the Lords will, everything will become more modernized, and it will cost a whole lot more to purchase a new phone in the future. Hopefully, Jesus Christ will come back to earth and restore harmony throughout all of the nations of the world.  There would be a new heaven and a brand new earth during that time. At least all of our worries will become a thing of the past.  If the Lords will, I will live to see it with my own eyes.  I have to literally prepare for something like this by making simple changes in my own personal behavior.  I am hopeful that this will become a reality within a 20 year period.  Thank you for allowing me to answer this question to the best of my ability.  In Jesus name Amen and Amen ❤️ 🙏 🙌 👏.  God Bless All of You Worldwide Amen 😊 🙏 🤗 ☺️ 🙌 👏.
