The best protection against demons and evil spirits is to attend mass regularly, go to confession and have a regular, consistent prayer life. We receive grace from Jesus, through the sacraments and prayer, and by genuinely living by God’s commandments.

Wrong.
We receive grace through Jesus Christ, not religion or religious works.
God LAVISHES it on us through Him.
He does not dole it out in stingy little parcels based on works man performs.
Ephesians 1:3-10 Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places, even as he chose us in him before the foundation of the world, that we should be holy and blameless before him. In love he predestined us for adoption as sons through Jesus Christ, according to the purpose of his will, to the praise of his glorious grace, with which he has blessed us in the Beloved. In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace, which he lavished upon us, in all wisdom and insight making known to us the mystery of his will, according to his purpose, which he set forth in Christ as a plan for the fullness of time, to unite all things in him, things in heaven and things on earth.
