>How do I stay focused in doing God's Will?
Study it and meditate on it, contemplate your life and actions. When facing trials, draw your mind back to the scriptures and the wisdom of the saints. And of course, pray frequently and fervently for the grace, strength, and the guidance of the holy spirit to lead you to the path of righteousness.
