Ephesians 4:17 This I say therefore, and testify in the Lord, that ye henceforth walk not as other Gentiles walk, in the vanity of their mind, 18 Having the understanding darkened, being alienated from the life of God through the ignorance that is in them, because of the blindness of their heart: 19 Who being past feeling have given themselves over unto lasciviousness, to work all uncleanness with greediness.
The Greek word aselgia (rendered lasviciousness above) is hard to understand for English speakers because it is used in varying contexts. The word itself means unrestrained living or unbridled indecency that shocks the public. In the above passage, it probably refers to homosexuality for it is coupled with uncleanness which is often a synonym for homosexuality (Romans 1:24, 26–27; Galatians 5:19). That said, the word can also refers to fornication and gluttony. One of the problems with the modern Church is its acceptance of aselgia – that is, its acceptance of members living unrestrained lives whether it be homosexuality, fornication, or gluttony. Of course, the argument against my view is that Jesus Christ is the great physician and only those who are gravely sick come to him for healing. I don’t disagree with that, but I also don’t see a whole lot of healing going on. To put it another way, victorious living marks the Christian, that is why the word “victory”, or “overcome”, is used over and over in Revelation to describe the faithful. Or, as John said in his first epistle, For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith.
