God knows you are not perfect, if you were you would not be human.You made a promise while fucked up,even our courts won't hold you to it.If you made a real promise you should keep it,but at worst you would be unreliable not evil.
God is not out to get anyone,your own actions punish you,not God. He is not so petty as to condem for being wrong, He made us warts and all, he loves us anyway.Any time you feel fear it is not from God.God is light God is love
