How can a Gentile (Me) pray to Hashem? How does a Gentile pray to Hashem? What format does a Gentile have to pray?
The best way to speak to Hashem is straight from your heart in your mother tongue. You need not pray in Hebrew, and need not say the prayers in the Jewish prayer-book, but simply speak to your Father in Heaven with the proper respect you would also give a King. If you want, you can utilize a Jewish prayer-book to give you ideas and help educate yourself to what a person should praise/ask/thank God, and in general, what we should want out of life. All the best!
