Everyday there are people who are evil. Look at the news. People are findings ways to inconvenience others. Whether it is people that hack the Internet, or people that harm others, there are many people who think only of themselves. Do these people worry about salvation and what would happen in the after life? Probably not since selfish people usually do not have long-term goals. But what would change their behaviors?
How about if God would shorten the time lapse between cause and effect of the law of causality? The law of cause and effect state that good thoughts and actions bring forth joy, and evil (greed, arrogance, and self love) thoughts and actions bring forth suffering in the future. But the time lapse between cause and effect is usually prolonged, making this relationship difficult to understand for the selfish mind.
Suppose God places illness or disease on the body, shortening the time interval between cause and effect. Would these selfish people understand God’s guidance or would they fear God’s wrath? Whether they understand God’s guidance or fear God’s wrath does not matter for law-abiding citizens. Their evil actions will probably subside. But for God, the intention is to purify the mind by guidance, and not punishment.
It is this guidance from God that we pray for daily. We pray not to punish the evil, but to guide them to eliminate the evils in their minds. When disease or illness is manifested, we hope that these inconveniences are not thought as punishment, but as God’s guidance. When the mind becomes pure, the illness is returned to God, and the future becomes joyous (the law of cause and effect).
