But surely it was no other sin than this, the keeping of bad company.
There was Eve in the garden.

God had provided her with company; He had given her Adam, the holy angels came in and out of that fair paradise; nay more, God Himself was her friend, in the cool of the day He walked with Eve under the trees of the garden, walked and talked with her as a companion and friend.
But, in spite of this, Eve got into bad company.

She stands, she talks, she entertains Satan, the great enemy of God, against whom she must often have been warned by God and the holy angels.

And the consequence was that Eve lost paradise, became a sinner, and brought sin and all its attendant miseries into the world.

We should never have had our weary battle with sin if Eve had not kept bad company.
Nor was Eve the last of those who have brought trouble on themselves and others by the same sin.
If the descendants of Seth had not kept bad company and made friends of Cain's wicked race, the flood would never have swept them away.
