There has been a lot of great spiritual advice on this thread. If I may, I would like to offer some practical advice...1Co 6:18 Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body.1Co 10:14 Wherefore, my dearly beloved, flee from idolatry. 1Ti 6:11 But thou, O man of God, flee these things; and follow after righteousness, godliness, faith, love, patience, meekness. 2Ti 2:22 Flee also youthful lusts: but follow righteousness, faith, charity, peace, with them that call on the Lord out of a pure heart.Praying and asking God to help us fight against our flesh is certainly scriptural, but there are also a lot of references to "fleeing" from sin and temptation.You can certainly confront this woman you work with, and witness your Jesus to her, and the Holy Spirit can impress that upon her heart and convict her of her own need of a savior.But let me also tell you... you are playing with fire here. You need to distance yourself from this women. You may even need to quit this job and go to work somewhere else. Move to another state if thats what it takes to maintain your purity, and your marriage!Imagine what it will be like to go thru a heart wrenching divorce. Imagine the day your wife finds out that you're having an affair. (I know you havent actually had sex with this women... I'm laying out what the future would be like if you let this go on too long) Imagine the look on your wife's face. Imagine the feeling of your face as you turn red from embarrassment. Imagine your family and friend's reactions when they find out. Imagine what it'll be like to lose credibility with everyone you know. And believe me, everyone will know what you've done. No one will trust you.And think of your 2 yr old son... not uderstanding why daddy cant live with him anymore. Your wife will have custody, and if your fortunate, you'll see him twice a month and every other holiday. You're wife will find a new husband who follows the Lord and is faithful to her, and before long he will be more a daddy to your son than you are simply because he's with him all the time under the same roof.And with God's grace your son hopefully wont grow up to be an angry teenager who gets into drugs.And imagine how it will feel when this woman that you have an affair with dumps you just after your divorce is final. All this for nothing!And even if you do marry this other woman... would you trust a woman who had adulterous sex with a married man?? But more than likely she'll dump you.So ask yourself... what measures are you prepared to take to save your family? You just gonna pray about it, or are you also gonna follow scripture and FLEE from this?And this all goes for internet porn too... unplug the internet if you cant control it. We all survived without the internet before the 90's... we certainly dont need it now. Get a filtering software and have your wife set the password. If your single, have your pastor set the password. Better yet, have your mom set it.Man, I'm telling ya... it's better to cut yourself off from this stuff than go anywhere near it!Mar 9:43-48 And if thy hand offend thee, cut it off: it is better for thee to enter into life maimed, than having two hands to go into hell, into the fire that never shall be quenched: Where their worm dieth not, and the fire is not quenched. And if thy foot offend thee, cut it off: it is better for thee to enter halt into life, than having two feet to be cast into hell, into the fire that never shall be quenched: Where their worm dieth not, and the fire is not quenched. And if thine eye offend thee, pluck it out: it is better for thee to enter into the kingdom of God with one eye, than having two eyes to be cast into hell fire: Where their worm dieth not, and the fire is not quenched.I struggle with lust just like every other red blooded man... in our society it is everywhere. But I am learning to cut out those things that would cause my heart to wander from my beautiful wife. It is a struggle, and I dont want this post to come off sounding like I'm exempt... I'm not. This was for me as much as it was for the original poster, and for those who have ears to hear. I praise God I've never cheated on my wife in the sense that most heathens consider "cheating"... but I can not say my heart has always been innocent. Jesus really backed us into a corner with that one. I really believe that that was His way of showing everyone of us that we have broken the Law... and need salvation.So I ask you, my friend... are you man enough to make some hard decisions? Are you man enough to do whatever it takes to get away from this situation? Or are you going to resist getting burned while standing in the middle of the fire? Let me assure you... you are not Shadrach, Meshach, and Abed-nego!Krispy
