You know that feeling you get when you first fall in love? You might feel it all over your body or it might be localized in your heart or even your teeth. It's a feeling of pure joy in the very cells and molecules of your physical being.
You might feel this feeling of physical joy at other times too, like when you see a baby or think about your children. Whenever that happens, don't miss it! Something profound has taken place. That's salvation. You've bumped into God.
