90 minutes in heaven

My other favorite quote from 90 minutes in heaven is on page 109. " So humble yourselves under the mighty power of GOD, and in his good time he will honor you. Give all your worries and cares to GOD, for he cares about what happens to you." My biggest question here is HOW DOES GOD LOVE YOU WHEN I NEVER SEEN HIM BEFORE AND I DONT KNOW WHO HE IS AND PEOPLE SAY THAT HE IS NOT REAL? I dont understand this at all. My comment on this quote is that GOD will love you no matter what and take care of your worries.
