“Faith in humanity” destroyed?

My heart was troubled upon seeing my friend (a Christian) reply to a shared blog with the caption “faith in humanity destroyed… again.” The blog was narrating a murder of a student where witnesses ignored the victim, not offering him any help. I know it’s not bad and I will not justify their lack of care. But the thing that worried me was the comment:
“…I do think the word justice and humane does not exist anymore in real life.” with a reply “exactly. justice, morality, humane, these words don’t exist here…”

Wait for a second, does this mean no one is just anymore, no one has morals, no one does humane things? What about us? Those genuine followers of Christ? What about these friends of mine?

Okay, maybe I’m overreacting. But isn’t God good, just, merciful, and loving? And doesn’t He still exist today? It means there’s still justice and goodness in this world. It doesn’t go extinct.

But…I suddenly thought, should we put our faith in humanity? Looking back at our history, should we trust humans’ natural moral compass?

I don’t know, but one thing I no is for sure: we can rely on God, and He has given us His Holy Spirit to direct our path. That’s why today, I pray for open eyes to see God’s love and goodness in this planet, open ears to hear his direction, and an open heart & hand to be God’s representative to every people I come across.

What about, how can you bring a message of love and hope to the people?
