Hey anon! Thanks for the kind words.
Immersing yourself in the faith always works. Read the Bible (or another religious text), attend Mass, attend other church events, etc. If you involve yourself in these sort of activities, you may become more invigorated by your experiences, and certainly you will be more inclined to think about it.
But in the end, faith is one of those three virtues that is supernaturally given to us by God. Man does not naturally have the gift of knowing that which God has revealed to us. As such, when you begin to lose faith, there is truly only one you can appeal to – God, whether through your own prayers or the prayers of the saints.
My advice to you, then, is to both immerse yourself in the Church and also pray about it. In trouble like this, I would usually pray to Saint Thomas Aquinas, the theologian responsible for helping me strengthen my own faith.
Thanks again for the question … God Bless!
