We become a better musician through practice, playing our instrument repeatedly in the hope of becoming a virtuoso.
We become a better farmer through practice, planting each year in the hope of yielding better crops.
We become a better athlete through practice, spending hours in the gym or on the field in the hope of excelling in our sport.

You can become more spiritual through practice, by finding some inspiration or revelation each day. With such practice, you will reach greater spiritual heights. If you hope of being touched by God, without practice you might not be adequately prepared for the experience.
