Overcoming a Deadly Offense
A deadly offense is an offense that if left unchecked it will cost you your life.
Sin is a deadly offense deposited by the devil against mankind, it is a spiritual parasitoid.
According to Wikipedia, a parasitoid is an organism that spends a significant portion of its life history attached to or within a single host in a relationship that is in essence parasitic; unlike a true parasite, however, it ultimately sterilizes or kills, and sometimes consumes, the host. Thus, parasitoids are similar to typical parasites except in the more dire prognosis for the host. An insect and especially a wasp that completes its larval development within the body of another insect eventually killing it and is free-living as an adult is a parasitoid.
Save yourself from a deadly offense
To be cured from a parasitoid, the host must be purged/purified of the offense, the parasitoid must be separated/cut off/removed from its host. Sin is a parasitoid that can only be cut off/separated or removed from within.
The only cure is Jesus Christ!
