A human religion?

(Horatius Bonar, "The Way Of Cain")

"Woe to them! They have taken the way of Cain . . ."
        Jude 11

Cain is not an atheist, nor an altogether irreligious man.

He acknowledges a God, and brings his fruits to the altar.

But he brings no lamb, no blood, nothing that speaks of death.

He comes with no confession, no cry for mercy.

He has a religion, but it is self made; a human religion,
something of his own; without Christ, or blood, or pardon.

Rejection of God's religion, and of His Messiah; this is
"the way of Cain."

"Woe to them! They have taken the way of Cain . . ."
        Jude 11
