@BigRon One of my favorite quotes is this: “Each of us is a result of a thought of God.”
You are here because God thought and loved you into existence; you are here because God desired you to know him, to be loved by him. If you didn’t exist, you would never get to experience love, or joy, or happiness, all of which God wants for you. Think of how rare it is to exist – all of the humans God has ever created are only a speck as compared to the infinite possibilities never created.
God loves you; we must suffer on this earth, yes, but God loved you so much he came to suffer with you. In fact, he suffered more than anyone ever will. And he did it out of pure love.
Why do you assume the probability you will end up in hell is so high? God has given every person what they need to reach heaven, to be with him. The bar isn’t too high. Will you fall? Yes. Everyone will. Again, and again, and again. We all make mistakes. Deliberately. But so did the Saints. All that God cares about is that you try. That you get up and try again. This is how you become a saint, and how you reach heaven.
Remember that God loves you and each person more than we love him; He so desperately wants us to be with him forever in heaven, so much more than we want to be in heaven. This is why he created us, and we must trust in his mercy and love that he will help us every step of the way in life so that we can remain in friendship with him and be with him after death.
Don’t despair; God is with you. Always.
As for the above passage, Jesus’ words here are meant for every one of us. It was a promise. We’ll always find Him in the Eucharist most completely.
