A lot of people tend to think that the ‘natural’ condition of human beings is to sin.
But Adam and Eve were created ‘without sin’.
Sin (original sin now, to us) is actually UNNATURAL. We now are predisposed to it because Adam and Eve fell, but this was not the way ‘in the beginning’.
This is why we refer to Jesus as the New Adam and Mary as the New Eve. . . two human beings who were likewise ‘without sin’ in their being (Jesus) and conception (Mary) and who, while capable of being tempted, ‘naturally’ did NOT sin.
Even now, every single one of us is capable of choosing ‘not’ to sin again. Hard? Yes. (Impossible, indeed, without God’s help --but with his help. . .we can do it).
So rather than assume (wrongly) that Jesus in His “humanity” was pretty much ‘bound’ to sin (rather than being, simply, ‘capable of being tested’ and thus as free to choose GOOD as evil), let’s consider rather that He and His mother, ‘human’ beings who freely chose to reject sin, should be our role models in life.
