“There is hope for whoever is among the living […]”
~Ecclesiastes 9:4

We should never give up hope on people, because even the most haughty can change for the better.
People’s circumstances change throughout their lives.
Some become more hard-hearted while others are softened as they recognize a higher power.
No one knows for certain the individual future of any other person, nor do we control our own.
“Time and unexpected events overtake them all” therefore “men cannot be certain of anything that will happen to them in the future.” (Ec. 7:14; 9:11)
Tragic events happen to everyone, whether they do good or bad things.
Blessings also happen to everyone.
In this imperfect world in which we live in, some things are only a matter of chance.
So is there any advantage to doing the right thing, even when it comes at a personal cost?
“It will turn out well for those who fear the true God, because they fear him.” (Ec. 8:12)
Those who have faith can be optimistic about their own long-term future and hopeful about that of others.
