The right object lesson can make a sermon principle stick for life. Harold Davis Ministries offers three products that no church resource closet should be without:

1. Snow Powder
   This absorbent powder expands into a snow-like substance whenever liquid is added.
2. Slush Powder
   This powder gels liquids into a solid.
3. Flash Paper
   This highly-flammable paper is designed to instantly burn up and create an exciting “flash” of fire.

Each one can be used to visually explain a variety of spiritual truths. Their only limits are your imagination.
