Practice. It often means doing the same thing over and over. It at least means regularly repeating things. Repetition. Form. Details. Progress.
Hard work. It usually means it isn't easy. Could mean pushing harder or going longer, or stopping when it's hard to. Hard work comes in many forms.
It's still the holidays for some of you -- perfect time to practice and get a little hard work in on an area you don't usually have time for. Like your inner life (things to mourn or let go of), a neglected instrument or relationship, or just sitting without doing anything for ten minutes. Or maybe doing something Jesus said, like visiting someone who is sick, in prison, lonely, in need. Or taking God seriously enough to do the thing you've known for years you need to do.
If you do I guarantee it will not only take grace and encouragement (translate wisdom and allies human and divine) but practice and hard work.
