The most important thing is to live by the will and not by the emotions

“Your emotions are unreliable. Indeed, they are like the waves. But you can abide peacefully by your will. What God wants to give is not a happy feeling every day. His purpose is for you to live by your will and your spirit. “I love the Lord, not because of what I feel, but because I want to love Him.” Just as we would read the Bible, pray, preach, and serve the Lord when we are joyful, in the same way we should read the Bible, pray, preach, and serve Him when we do not feel anything and our heart is as cold as ice. Please understand that the most important thing is to live by the will and not by the emotions. The most deceiving thing is for a person to take his feelings as an indicator of his spiritual life. From now on, please learn to exercise your will to control your whole being and your feelings. If God rewards you with feelings, thank Him. If He does not and you feel lost at heart, go on as usual. Until you have overcome your habit of living by your feelings, God cannot greatly use you. He needs solid vessels, those who do not change due to circumstances.”
