Are you sometimes sad about how people behave?
It can be especially disappointing if beloved people like family members ruin their lives, such as teenagers and young adults taking wrong decisions that ruin their health, their career, their lives, destructive decisions that they will regret later on.
People of all times got sad when seeing the destructive behaviour of others.
We can learn from those who also were disappointed in such a way and yet continued to walk closely with the Lord.
