Sir,
The crux of almost every religion and form of spirituality is built on the acceptance of two vital truths.
First is belief in a singular divine Creator and secondly to behave yourself to attain salvation. Everything else is detailed.
Humans are not all the same and different things motivate people. Some must experience suffering to learn to behave.
Others learn from seeing the suffering of others and learn the same lesson.
Reason
This is one reason why Jesus Christ may have inferred that you must love and not hate your enemies.
Even enemies have a role to play in one’s life.
Whenever the Israelites disobeyed God, He sent a prophet to warn them. When they refused to listen, God unleashed the wrath they had brought on to themselves.
To clarify; God does not punish as God’s mercy is greater than God’s wrath. However, there is a balance in everything.
Once that balance has shifted too far, rectification is required and wrath returns to balance.
Some of us are mediocre with limited ambition. Perhaps the Creator may want more from us.
Thus we may find ourselves in an awful work milieu or relationship from which we must escape.
Improve
Hence we either improve our qualifications or do whatever to get a better job or relationship, marriage, etc.
Though we may despise the people who, for whatever reason made life or work difficult, the result is that we may improve ourselves because of the infinite negative energy that surrounded ourselves.
Hence the saying; God works in mysterious ways.
