Becoming a Christian doesn't make you a super hero. It doesn't make you immune to or ignorant of the temporary pleasures flaunted by the world. In fact, choosing a Christ-honoring life is far from easy! Living righteously can be very, very difficult and will be unpopular. Often when someone becomes a Christian, previous sinful desires they possessed immediately drop, and they never stoop to that specific captivity again. However, we are still flesh and bones living in a sin cursed world, and there are plenty of temptations to keep us on our knees!
There are certain things in the Scriptures that God just tells us to flee, to avoid at all costs, to run away from, to not so much as pass by! (Note: trials should be embraced as allowed by God to develop inward character, teach others, etc., whereas sin should be removed from our lives hastily.) God knows what we're made of, and it is out of love for us that He commands we not handle sin lightly.
Know yourself. Know your weaknesses. Satan is not going to attack you where you're strongest, and you really don't want to contend with him where you're weakest. Resist him and he will flee from you.
Finally, make a game plan. A lot of people stop with I Corinthians 13:14:
God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it.
But the following action verse should not be overlooked:
Wherefore, my dearly beloved, flee from idolatry.
Be wise as a serpent and make no provision for the flesh. In fact set yourself up for success! This includes accountability, commitments, self-control, self-denial, and a vigorous walk with Christ. Don't stick around and see how much temptation you can handle - be smarter than that, friend.
God's will is exactly what we would choose if we knew all the facts.
Flee also youthful lusts: but follow righteousness, faith, charity, peace, with them that call on the Lord out of a pure heart. II Timothy 2:22
