Charles Ellicott Commentary 1 Corinthians 10:26

"for the earth is the Lord`s, and the fulness thereof." — 1 Corinthians 10:26 (ASV)

The earth is the Lord’s...—All food that earth brings forth or nourishes is God’s gift, and therefore good. It was only when regarded as an actual sacrifice that any meat could be considered to be "of devils." This great truth, recognized in the Old Testament as well as in the New, is the reason for the previous statement that conscience need not come into the matter at all.
