I had bought these little hand sanitizers a while a go when they were on SUPER clearance (I think $0.50 at the most). I knew I would tie them into a lesson sometime. It was kind of stretch but it worked?
We talked about how sometimes we use sanitizer to protect ourselves and sometimes we use it to protect others. Much like our spiritual gifts.
For example you may be given the gift of faith and never question the existence of God. You may be given that gift that others would believe on your words, that they might have eternal life if they continue faithful. (see here)
