Denis Diderot (1713-1784), who is best known for serving as contributor and chief editor of the Encyclopédie was a prominent French Philosopher, art critic and writer, during the 18th century cultural movement (known as Enlightenment or Age of Reason) among the intellectuals in Europe and America. Diderot is quoted to have said “The blood of Jesus can cover a multitude of sins, it seems to me.” Interestingly even though we often hear such a phrase in our churches, the Bible never directly talks about the “Blood of Jesus” as something that covers. However, extrapolating from a few other verses in the Bible, we see that the “Blood of Jesus is a Covering.”

1 Peter 4:8 says, “… Love covers a multitude of sins.”
Proverbs 10:12 affirms “Love covers all sins.”
1 John 1:7 states that if we have fellowship with God, the blood of Jesus his Son, cleanses us from all sins.
John 3:20 informs us that God loved the world so much that he gave us Jesus, his Only begotten son. Jesus is therefore God’s expression and personification of  love and by substituting the word ‘love’ with the Name ‘Jesus’ in the before mentioned verses, we get “… Jesus covers a multitude of sins” and “Jesus covers all sins“. Jesus covers all sins because his blood cleanses all sins. In other words, the blood of Jesus, the Lamb of God, covers all sins.

James 5:20 reads “.. he who converts a sinner from the error of his ways shall save his soul from death and hide a multitude of sins.”
During the exodus of the Israelites from the land of Egypt, the LORD passed over the houses that had the blood of an unblemished lamb on their doorposts. The blood of the lamb hid the residents and saved them from death. (Exodus 12:13, 23)
Only Jesus can convert a sinner from the error of his ways and save his soul from death and cover a multitude of sins, because Salvation is [solely] of the Lord (Jonah 2:9). The Blood of Jesus Christ, the Passover Lamb hides and covers all those who believed in his Name.

Points to ponder:
The Blood of Jesus is a covering. Have you believed in him, for in doing so, your sins shall be hidden from God’s wrath and your soul saved from death. In other words, Are you under the covering of the Blood of the Lamb?

1 Peter 4:8 (KJV)
8 And above all things have fervent charity among yourselves: for charity [love] shall cover the multitude of sins.

James 5:20 (KJV)
20 Let him know, that he which converteth the sinner from the error of his way shall save a soul from death, and shall hide a multitude of sins.

1 John 1:7-9 (KJV)
7 But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.

Jonah 2:9 (KJV)
9 But I will sacrifice unto thee with the voice of thanksgiving; I will pay that that I have vowed. Salvation is of the Lord.
