Is there a sin that is worse than the devil?
Listen to what the Puritan John Owen wrote:
"Impenitent unbelievers under the preaching of the gospel are the vilest and most ungrateful of all God's creatures. The devils themselves, as wicked as they are, are not guilty of this sin, for Christ was never offered to them. They were never offered salvation on the condition of faith and repentance. This is the terrible sin of unbelievers and will greatly add to their misery in hell." (The Glory of Christ, ch. 14)
God never offered salvation to the fallen angels. He never gave his Son to save them. When man sinned, God owed us nothing, either. He could have given us the results of our choice and a fate similar to that of Lucifer and his angels. BUT (praise God!) instead, God chose to act in love, mercy and grace to fallen man! At great cost to himself (the death of his own Son) he showed off the glory of his grace to rescue us from our dilemma. Christ died for sinful man. Christ is now offered to sinners.
In light of such beautiful grace, what a hideous sin it is to reject Christ!! What a slap in the face of God! Satan has never committed such a sin - rejecting an offer of a crucified Christ in his place - but hell will be filled with rebellious men who have done just that.
Reject him no longer! Look to Jesus and be saved!
"Come to me, all who labor and are heavy laden, and I will give you rest...and whoever comes to me I will never cast out."
Matthew 11:28, John 6:37b, ESV
