What the Bible says about Creating Own Standards of Righteousness
(From Forerunner Commentary)
Immediately after their sin, and the knowledge of what they had done began to dawn on them, Adam and Eve immediately begin to “make do,” to adapt. This is illustrated by them making clothing for themselves. Quality of clothing is later used in the Bible as a symbol of the quality of righteousness, and their “making do” shows us that they were creating their own standards of righteousness. To add insult to injury, they hid from God when they knew He was about.
