We cannot only pull through on big matters, and let small matters fall through the cracks, that isn’t the right way to do things.
For instance, a worker cannot only do the larger tasks his boss asks him to do, then ignore the small tasks, he would be fired.
We can’t only avoid things we know to be gravely sinful, then brush off the things which would be venially sinful. As the Catechism teaches us, mortal sin separates us from God, takes away sanctifying grace within our souls, and if we die in the state of unrepented mortal sin we will go to hell for all eternity. But venial sin though not grave is still wrong.
Here is an example. Think of your bond with God as a brick wall. Mortal sin is like taking a wrecking ball to that wall and destroying it. Venial sin, on the other hand, is like taking down the wall one brick at a time. Not as grave, though still destructive.
So all things matter, big and small. How can we claim to be close to God, wanting to love Him more fully, striving to grow closer to Him when we only care about the big things and turn away from the small things. The small slights we throw at our Father, the small times we decide we don’t care because it’s such a minor matter, it’s only once, it’s only venial. But one thing which still remains even though we may convince ourselves it doesn’t matter... it’s still sin.
Do not ever get comfortable with sin. As soon as you let the Devil get a foot in the door of your soul, it is that much harder to keep him out.
God bless you all, talk to you soon, Zac.
