It must be done from the heart.

"To make a house into a home it must be done from the heart." This works for just about anything. If you want something to be or feel home-y or anything else, you have to do it from the heart. Service must be done from the heart. Repentance must be done with a broken heart and a contrite spirit. Prayer must be done with faith, and it can be done from the heart. To become Christlike, it has to be done from the heart.
