1 Corinthians 10 v 25-26


1 Corinthians 10:25-26 
(25)  Whatsoever is sold in the shambles, that eat, asking no question for conscience sake: 
(26)  For the earth is the Lord's, and the fulness thereof. 


10:25-26. For a Christian who bought meat at a market with the intent of eating it at home, Paul recommended that selections be made without reservation. No one could contaminate what God had made clean (cf. Acts 10:15) since everything belongs to Him (Ps. 24:1).
