Being tempted is not a sin...Jesus was tempted in the desert, yet was without sin (Hebrews 4:15 For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin.
Pretty sure the context of the discussion lies in the age-old discourse over Thought, Deed, and Opportunity. Jesus said this: "You have heard it said, 'Thou shall not commit adultery,' but I say to you that any man who has lusted after a woman has already committed adultery with her in his heart..."
Thought, Deed, Opportunity. I'll break it down...
Easily enough, part of this discussion lies in opportunity...If one lusts after a woman but does not have the opportunity to commit the deed, he is guilty of committing the deed in his own heart. Therefore, his thoughts and his motives were sinful, even though he did not commit the deed, merely because he had no opportunity. This man would confess his thoughts and heart IN THE SAME MANNER as if he had committed the deed...
Now, for the man who HAS the opportunity...In Dago's example, a man was tempted, had the opportunity, but abstained from the deed...Mash says he would be just as guilty as the man who went ahead and did the deed, and for this reason, Dago counters with, Then why doesn't he just go ahead and do it if abstaining doesn't make him any less culpable...that's the gist of the discussion, right?
Here's the answer...Being tempted is not a sin; the man who is tempted but abstains is not culpable to that temptation. IF that temptation leads to lustful thought, he is guilty of those thoughts...and IF those thoughts lead to action, he is guilty of an even greater abomination...(Yes, there are levels of sin...Ezekiel 8 speaks in depth of "Greater Abominations"; also 1 John 5 talks about "sins NOT unto death, and sins that ARE unto death" ; not all sin is equal...we could talk more about that if you'd like...)
Hear this truth:
1 John 5:4 For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith.
1 John 5:5 Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?
1 John 2:16 For all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world.
John 16:33 These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world.
Here is the truth. We are to overcome the world. The world has THREE things in it that must be overcome: The lust of the flesh, the lust of the eyes, and the pride of life.
To see a woman and lust after her is the lust of the eyes; it is sin. To act upon that lust is the lust of the flesh; it is also sin...which COMPOUNDS the original sin (the lust of the eyes; that is to say, the lustful THOUGHTS) into what the Bible calls SIN UNTO DEATH...
16 If any man see his brother sin a sin which is not unto death, he shall ask, and he shall give him life for them that sin not unto death. There is a sin unto death: I do not say that he shall pray for it.
17 All unrighteousness is sin: and there is a sin not unto death.
And for clarity's sake, SIN UNTO DEATH are the sins which would keep you or I; even any CHRISTIAN (because the Bible was written to Christians, right?) from inheriting the Kingdom of God...
Ephesians 5:5 For this ye know, that no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God
1 Corinthians 6:9 Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,
1 Corinthians 6:10 Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.
19 Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,
20 Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
21 Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.
That is the answer.
