Imo the meaning of life isnt really a mystery. God told man to "be fruitful and multiply"
Just expand and manifest your best self, your best love and interests in reflection of the universe. The universe is constantly expanding in all directions, even the earth is in a state of constant change and evolution. We are made of those same atoms, we are doing the same thing the MEANING is can you get that to bear fruit?
To multiply is our responsibility to share, care for, better and correct each other and our offspring. I think recent technology has caused huge leaps in this area.
Edit --- on "fruit" from Galatians - But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness and self-control.
