I am very glad that I became Catholic all those years ago. However, I am very grateful for what I received/learned as a child from various Protestants. I was raised to believe in God, and I appreciate that. I was raised to love others. I learned to read the bible and listen to Jesus. I was told to worship God, not just in my room, but together with other Christians. Things like this. God used these and other things to lead me to be confirmed in the Catholic Church. Once here, I learned so many things that I am so happy I learned! I belong here. I always wanted to sit at the Master’s feet, and here I can do that best, plus more than I ever imagined. He is the way and the truth and the life. There is no reason to leave such a place, until He takes me home.
If you are looking for a specific thing that is “more” for me here, it is the Eucharist and communion with the Trinity. As a result, I have more appreciation of heaven than I did as a Protestant. I used to not care about it, because I only looked upon it as a place with no tears. I didn’t see that as offering much more than total oblivion did. I’m trying to think of concrete terms, rather than a theological description, to help you see what it means to me. I guess you could say that before, despair lurked on my doorstep. Understanding God’s plan of salvation changed that.
