Here are the four mysteries, which are of high importance for our faith:
The first is to love your enemies and to wholeheartedly forgive them.
The second is to find a spiritual master and to tell him: “I, my Father, I have to repent because I do not love God and my brother.” I am ungrateful to my God for the very good that He has given me. You should confess all your sins without any shame.
The third is when the spiritual reprimand you, you do not put the blame on somebody other. You should take the blame, only you are responsible for everything that happened to you.
The fourth is that you should consider all that your spiritual master will advise you, and you should tell clearly that you had better die, rather than to fall again and commit the same sins.
After the confession you should participated frequently in the Holy Sacraments, since death stealthily moves in as if it were a thief and if we drop dead, what will we do?
