1 Cor 1:18 For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.
The world calls the cross foolish. What they fail to understand is that Jesus’ crucifixion is our salvation because Jesus became sin for us.
“All of heaven is interested in the cross of Christ, hell afraid of it, while men are the only ones to ignore its meaning.” ― Oswald Chambers
