First of all...
First of all, you must define 'the God of you're understanding,' not anyone else, someone, whether it be a He, She or It. Who is personal to you...and whom. Initially at least you can say the Serenity Prayer to, as often as you like, God likes the sound of a strange voice! In this way,you develop self belief and and when you believe in yourself, others believe in you....
'If you believe in God, he will not care how devout you are, but what a good person you are.
If your God is an unjust god, you wouldn't want to worship him anyway.
If you don';t believe in god, you should still be a good person anyway,, then when you die. You're loved ones will have good memories of you.' - Marcus Aurelius
