Why do you say "God's right hand is merciful and his left hand is horrible"?

The Bible says that those who are touched by God's right hand can get God's blessing, and those who are touched by God's left hand will get curse and disaster.

This sentence means that even God has two sides. We can't just pray for something in return, or there will be something in return.

Another meaning is that everything has its negative side, so we should look at things objectively.
