John says that "all that is in the world is the lust of the flesh, lust of the eyes, and the pride of life." I don’t want to use this as a key to unlock other passages to make them say what they don't mean, but I have found this text as a helpful key in grasping what sin is.
The first sin and temptation was is in the garden. I see this paradigm applied there. The next sinless human on the scene, the Second Adam - our Lord Himself, was lured by the tempter in the same three ways. Finally, God's wrath comes upon mankind in three ways and for three reasons in Romans 1. I see John's "all that is in the world" in this tri-degradation as well.
So, here is all of the above charted out.
"We don't have a high priest who cannot sympathize with our weaknesses, but one who has been tempted in all things as we are, yet without sin. Therefore, let us draw near with confidence to the throne of grace, so that we may receive mercy and find grace to help in time of need" [Heb 4.15-16].
