βIf I had not come and spoken unto them, they had not sin: but now they have no cloke for their sinβ (John 15:22).
What on earth did the Lord mean here when He said that if He hadnβt come, the unbelieving Jews He had mentioned in the previous verse βhad not sinβ? Surely they had sinned, whether He had come or not!
To find out what He meant, we have to define a word that we donβt use very often, the word βcloke,β spelledΒ cloakΒ in our day and time. A cloak is a loose, sleeveless garment that is worn over other clothing, and about the only time that this writer hears the word even mentioned is when someone puts theirΒ coatΒ inΒ the cloakroomΒ of a restaurant.
Now the thing about a cloak is that you can easilyΒ concealΒ something under a loose, sleeveless garment, such as a dagger. This has given rise to the expressionΒ cloak and dagger, a figure of speech that refers toΒ espionage. For this reason, when this word is used as a verb, toΒ cloakΒ something means to hide it.
All of this helps us understand what the Lord meant when He said that if He hadnβt come they would not have had sin. He didnβt say βthey had not sin, then I cameΒ and now they have sin.β He rather said, βThey had not sin, then I came and now they haveΒ no cloakΒ for their sin.β In other words He was saying, βNow that Iβve come, they canβtΒ hideΒ their sin any more,β and I believe He had aΒ specificΒ sin in mind, an all-encompassing one that He mentions in the next verse.
βHe that hateth Me hateth My Father alsoβ (John 15:23).
The comprehensive sin that these unbelievers were cloaking so successfully before the Lord came wasΒ hatred of the Father. Since the Law commanded the Jews toΒ loveΒ the Father (Deut. 6:5), it was a sin to hate Him, and for centuries unbelieving Jews had cloaked their hatred for GodΒ with their religion, which provided the perfect cover. Practicing Judaism made it appear that unsaved JewsΒ lovedΒ the Father, but as the Lord said of them: βThis people draweth nigh unto Me with their mouth, and honoureth Me with their lips;Β but their heart is far from meβ (Matt. 15:8 cf. Isa. 29:13).
If you are wondering how the Lordβs coming uncloaked their hatred of the Father, remember that He represented God the Father in the flesh, and so when He showed up and they hated Him, it showed they hated the Father.
But notice in our text that it wasnβt just the LordβsΒ comingΒ that uncloaked their sin. He said, βIf I had not comeΒ and spoken unto them, they had not sinβ (John 15:22). How did His words uncloak their hatred? Well, remember, His wordsΒ were the Fatherβs wordsΒ (John 3:34; 8:26; 12:49). So when the Lord spoke the words of the Father and they hated His words, they were actually hating the Fatherβs words! source
