Brother, Jesus died for the sins of all mand kind ,He redeemed all man kind , His death for our sins redeemed and saved us’ BUT, only those who, by God’s actual grace ,accepted that redemption are saved, He died for all of us. What you are missing is , that the process does not stop there. Let’s talk about present and future sins. YES, he forgives them but only if, when we sin now or in the future, we repent of them and seek forgiveness other wise we burn in hell.
I understand that what you said in your above post is what the believers of Once Saved always Saved are all about,That is false doctrine.
We work out our Salvation in fear and trembling, as Paul says,throught the gift of sanctifying grace which God gives us when we are Baptized and justified. It is a life long process, the Holy Spirit working in us to make us holy.
You want to learn Catholic Theology from some one other than a simple person like me??? Open a copy of the Catechism of the Catholic Church. Listen to what the teaching authority of the Catholic Church has to say(The Magisterium) If you do it ,calling upon the aid of the Holy Spirit, you will come away converted.




God love you! CArlan
