for the Lord's <FI>is<Fi> the earth, and its fulness;
for the Lord's <FI>is<Fi> the earth, and its fulness;
1 Corinthians 10:24 let no one seek his own--but each another's.
1 Corinthians 10:25 Whatever in the meat-market is sold eat ye, not inquiring, because of the conscience,
1 Corinthians 10:26 for the Lord's <FI>is<Fi> the earth, and its fulness;
1 Corinthians 10:27 and if any one of the unbelieving do call you, and ye wish to go, all that is set before you eat, nothing inquiring, because of the conscience;
1 Corinthians 10:28 and if any one may say to you, `This is a thing sacrificed to an idol,' --do not eat, because of that one who shewed <FI>it<Fi> , and of the conscience, for the Lord's <FI>is<Fi> the earth and its fulness:
The verse centers on "lord's", "earth", and "fulness". It is saying that the verse draws attention to "lord's" and "earth", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 25's "Whatever in the meat-market is sold eat..." into verse 27's "and if any one of the unbelieving...", so "lord's" and "earth" belong inside that flow. In 1 Corinthians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "lord's" and "earth" with trust shaped by these words, not by a vague optimism outside the passage.
