Any fear that keeps you from church because "you might get sick" is an unreasonable fear: God commands His people to assemble. Ours is to obey, and if He send a pestilence to sicken us while we're obeying, at least we're obeying, and we know that He does all things well. God can just as easily keep us well while we obey as sicken us while we take every precaution known to man.
It is specious to say that we are tempting God if we run a risk in order to obey. God requires obedience in spite of risk, and will not hold us vain tempters of Himself if we suffer danger in order to obey.
Those who from fear will not assemble show that they do not believe that God will honor those who honor Him. They fear the wrong thing: God is to be feared more than any other danger and respected more than any other dignity.
"However, no need to talk about risks that lie in the way of one's duty. It is unnecessary risks that we must avoid."
-Mr. Gibson in Elizabeth Gaskell's Wives and Daughters
