Similarly, God gives us a sex drive to bond couples and families, and perpetuate humanity. Because it is a powerful drive, it is easily perverted and redirected away from its intended purpose.
IMHO, these natural tendencies are better viewed as gifts to be cherished, respected and applied in the context God intended, rather than resisted or, "overcome." Letting them run rampant and control us, is of course, a grave sin, but locking them away and repressing them altogether is neither what God intended.
Luckily, God has given us an, "operator's manual," that pretty much guides us through the proper uses and application of these impulses, instincts and drives He provided us as standard equipment. They are things to be channeled and tamed, not ignored or repressed altogether.
So to the addict who is hooked on crack, a little bit is not bad? Or to the sex addict who is hiding his affair, a secret rendezvous (with someone not his wife) is not bad?
Is Christ wrong that a 'little leaven spoils the whole lump'?
No, there are no halfway measures to deal with temptations and lusts. Halfway measures are total failures with both of these and are just as deadly.
Thank you for that observation Joe, it helps.
