The person who is tempted on a daily basis and gives into temptation because it is his daily choice is really not being tempted at all. For the Christian, however, who is tempted from time to time by a specific alluring desire, the concept of temptation is very real.
What's especially difficult to endure is when temptation comes when least expected. Sometimes a Christian does not go looking for temptation; it comes to him or her. At the time the temptation comes the shock value of being tempted by a specific allurement may leave the Christian unprepared. Only through a merciful turn of events can the temptation be sidestepped until there is time to pray and fortify oneself with the word of God.
Perhaps one is tempted to think that one's faith experience is false since temptation almost got one where it would have hurt the most. However, the best solution is to chalk it up to the mysteries of the Christian life and not decide that one's desire to follow Christ is somehow not sincere. Temptations come and go. We need to live through them and not get discouraged.
It also is unrealistic to live in fear of temptation and to lock yourself in your home so as never to be tempted. Christians are not called to be hermits. Of course, depending on your particular set of temptations, you may have to change your daily routine. But, again, don't live in constant fear of running into an old friend, or of accidentally finding yourself in the chocolate aisle at the supermarket when you had purposely avoided that aisle so as not to be tempted with your old chocolate addiction.
Remember that no temptation is worth giving up the hope of eternal life.
The phrase "the best temptation of all" was coined by Richard Baskin in "Welcome to L.A."
