You cannot save the world.....
But you can make a difference!
"21 Keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life. 22 And of some have compassion, making a difference: 23 And others save with fear, pulling them out of the fire; hating even the garment spotted by the flesh. (Jude 21-23)
You're invited to make a difference. It's their eternity.
It's your responsibility.
