It's a Gospel presentation "that will get tossed, but never into the garbage!" runs the sales blurb. From the top, it looks like any old secular frisbee. But underneath is a lot of small print about the gospel called "making your life fly right".

"Slip it to a stranger, neighbor, or friend, then flip it over to share how to throw it and how to have a new life in Christ. The Gospel is on the bottom of the disc... The Parable of the Lost Son is used to explain God's unconditional love and forgiveness."

So next time you are relaxing on the beach – and an overly-cheerful tourist clutching a dozen, innocent-looking plastic discs approaches you – flee at once to the sand dunes.

For your frisbee of faith, throw $2.20 in the direction of Slip Disc Ministries.
