Pray, attend church, BELIEVE and nurture the faith you have, and remember no one is perfect.
Why? He doesn't exist. (neither does the tooth fairy)
The best way is to pray , read your bible , attend church as often as you can ! Those who do not believe in God are just ignorant and can not comprehend him or much of any thing else ! These people are just ignorant and probably do believe in Santa Claus ! They can not explain who or what made everything that was made and who or what made everything and everyone ! They are not mature enough to believe in God the way intelligent people do ! Thanks
