May Yahweh Alone be praised, Masauko! Do your part, that is, cut off what is making you struggle with lust. Prayer only does so much at times. Play your part, that is live a pure life and guard your eyes (what you watch, read, fantasize on, etc).
May the Holy Spirit help you in your efforts as you cooperate with Him, in Jesus’s Almighty Name I pray, Amen!
