Take that rash to the Lord. Early.

Scripture:
“When anyone has a swelling or a rash or a shiny spot on their skin that may be a defiling skin disease, they must be brought to Aaron the priest or to one of his sons who is a priest.
Leviticus 13:2 NIV

Application:
A rash may be harmless, or it may be fatal. We don't always know, so it should be looked at. Something that's abnormal has to be diagnosed before it spreads, threatening not only us, but also those around us.
Our hearts or minds may contain something troubling. It may seem little now, but left unattended, it may grow and send us to hell and make life horrible for others.
Our doctor is Jesus. Take every concern to Him. Do it early, before it kills.

Prayer:
Lord Jesus, we know so little about the many ways that a small problem may become a huge problem. We're bringing every problem to You, praying that You will save us and those around us before it's too late. Amen.
