The issue is not going to church; rather, the issue is worshipping and renewing covenants as we attend church. The issue is not going to or through the temple; rather, the issue is having in our hearts the spirit, the covenants, and the ordinances of the Lord's house. The issue is not going on a mission; rather, the issue is becoming a missionary and serving throughout our entire life with all of our heart, might, mind, and strength.
Our sincere desire should be to have both clean hands and a pure heart - both a remission of sins from day to day and to walk guiltless before God.
The Book of Mormon is our handbook of instructions as we travel the pathway from bad to good to better and strive to have our hearts changed.
