Well, actually pandemics ARE the result of willful sin. Before the willful disobedience of Adam and Eve in the garden there were no pandemics or diseases of any kind. Mankind has been suffering the consequences of the original sin and our own ever since the garden was closed off to man. Now the earth is stained and deteriorating as the result.
The point I was really making, though, was that there is a way to not fear any outbreak of any disease or sickness and that way is through a relationship with God the Father through His son Jesus Christ.

"In the beginning God...", this is how God's Word to us begins. When we fail to embrace this great truth, we fall prey to the lies so readily offered by the evil one. Almighty God has offered us One Way to escape the ravages of our willful sin (anything that offends God's Holiness) in His Son, Jesus Christ. Actually Christianity is not a religion but rather the person of Christ Himself. To all who have believed on Him, there need be no fear of ANYTHING. He gives instead a spirit of power and love and a sound mind.
In fact He said, "In this world you will have tribulation, but be of good cheer; I have overcome the world." Find a Bible, read it, choose life.
