How does temptation lead to greed?

Temptation doesn't lead to greed. Greed is second-nature to the flesh... like lust, envy, jealousy. These things naturally rule over the flesh with the desire to sate any and all of the five physical senses of taste, touch, smell, sight and hearing.

So, temptation doesn't LEAD to greed [or envy, or lust, or jealousy]; these things that ARE what we are. Temptation merely FEEDS them.
