From Creation and Change by Douglas Kelly, Professor of Systematic Theology, Reformed Theological Seminary, Charlotte.
Even more theologically significant is the clear Biblical teaching running throughout the Old and New Testaments (as in Genesis chapter three and Romans chapter five) that death and disintegration of the entire cosmos came through Adam's sin, for Adam was the covenant head and representative of the whole creation, not Lucifer. Althought Lucifer fell before Adam, his fall did not bring death into the rest of the created order, because Adam, not Lucifer, was the representative figure (or 'covenant head') of the whole creation, thus taking it down with him into judgement.
