Ask anyone who has played much basketball to show you their free throw routine, and they will know exactly what I am talking about. They would be able to instantly show you what ritual works for them before they shoot. Don’t believe me? Ask, and they can demonstrate.
The reason these routines exist is simple: They work. Shooters that have a specific routine tend to shoot better. It is a combination of relaxing, taking inventory of your mechanics, and confidence. Any good coach will encourage a player to work out his/her routine, and practice it so much that it becomes “automatic.” It is a mental part of the game.
There are elements of our spiritual preparation that seem to work best if they are part of a routine. Specifically personal scripture study and prayer, and family scripture study and prayer.
