"Why if the Bible is God's word and the church his house, do they have lightning conductors." Matthew Chamberlain
For the same reason church buildings have a roof. It rains. Contrary to popular opinion, being struck by lightning isn't a sign of divine displeasure. Christians get wet when it rains, bruise when they fall, and sometimes die when they are shot. If a Christian is hit by lightning if would be because he is standing in a vulnerable place. Still, if he is a Christian, he has everlasting life so his death is nothing serious.
