One of the spiritual practices that helps me get through daily struggles and difficulties is to recall how God redeems our gifts, personal histories, and even our eccentricities for His own purposes. This is one of the ways I try to work to stay grateful. Gratitude saves us from a multitude of sins and distractions. Here's an example from my own ministry.
Yesterday I had a large funeral Mass to offer, and the family had been very diligent about planning it. I wanted to try to make some extra effort for them, so I tried to sing some of the Eucharistic Prayer, which I had never done before. It wasn't anything grand, just EP III from the Memorial Acclamation to the Doxology from the simple notation (only three notes!) in the back of the Sacramentary. I was very nervous. It wasn't great, but it came out o.k.
After Mass I was thinking of the hours and years spent with the 'alpha female' music teacher in my elementary school, being put through the Kodály Method and standing there wondering what on earth could be the use of singing "Sol-Do-Sol-Do" over and over. I even remember the hand signals that went with it. But here I am, thirty years later, putting it to practical use for the glory of God, singing the Eucharistic Prayer. That's the way God works.
