I know God is real

I know God is real because I've seen Him in the face of a stranger, being kind to me and reaching out a hand when I didn't wanna try anymore. I've heard God when I go to church and the preacher happens to talk about exactly, I mean word for word,what I'm going through. Or when I turn on the radio randomnly and a song is playing that calms me and is just what I need to hear. I've prayed and received no answer but I've also prayed and received many answers. He's not going to walk in and sit down in front of us, but He is always with us.
