Religion and God is and has always been (IMO) a way for humans to gather society together in some kind of cohesion and civilization. Rules, societal order, all that. As we evolve, so does religion (unsurprisingly!)
Maybe God is a way for people to take concrete steps to do the right things by one another. It really is what the 10 commandments and golden rule boil down to. Be nice, do good. Don't harm each other. Atheists, humanists can see the value in that even when it isn't faith driven. All religion basically comes down to those principles, but we also recognize that we often fail at this no matter what we believe about God, Forgiveness is desired and we want to go forward and learn from our mistakes. (Mercy of God or man)
Don't deaden the light in your eyes by blowing off your life, your health, family, work and healthy sexual relationships. Those things matter even without a God ruling your life.
JWs and most religion focuses on our fears and desires. Our fear of being beyond redemption and our desire for peace and safety. Some people ascribe the redemption to the religion, but you need to be merciful to your own self and seek out the things you want in this life that benefit you and make you happy. So what if there is no God! There are billions of other PEOPLE on this world, most of whom have it a lot worse than ANY of us. You hate religion? You don't believe in God? Do you want to prove the controlling cultish relgion RIGHT or do you want to prove them wrong?
You can be a good example or a cautionary tale. Don't be a tool to con some other poor suckers.
