Both St. Paul and Jesus have encouraging words for us in today's Scriptures: keep trying, be encouraged, don't give up!
Achieving anything worthwhile is difficult - moral goodness is no exception. One important way to keep encouraged is by prayer, especially Eucharistic Adoration.
Stop in and spend some quiet time with Jesus in the Blessed Sacrament on Wednesdays during the day or on Thursday evenings. Even one hour will make a tremendous difference to your entire week.
