Here's the scenario.

Someone has accepted Jesus as their personal Friend and Saviour.

From time to time that someone (lets be honest... me) will give into temptation and commit a private sin (one that only God knows about). After which I am extremely repentant and sorrowful. IF this happens infrequently but over a long period - Will God always forgive me?

I know that I should not sin, but from time to time I will have a moment of spiritual weakness and lapse. I (we) are surrounded by sin all the time (television, magazines etc). Should I not watch television (to metaphorically pluck my eye out) or should I be more prayerful?

Proverbs 6:14-15
In whose heart is perverseness, Who deviseth evil continually, Who soweth discord. Therefore shall his calamity come suddenly; On a sudden shall he be broken, and that without remedy.
