(the Lord grant unto him to find mercy of the Lord in that day); and in how many things he ministered at Ephesus, thou knowest very well.
(the Lord grant unto him to find mercy of the Lord in that day); and in how many things he ministered at Ephesus, thou knowest very well.
2 Timothy 1:16 The Lord grant mercy unto the house of Onesiphorus: for he oft refreshed me, and was not ashamed of my chain;
2 Timothy 1:17 but, when he was in Rome, he sought me diligently, and found me
2 Timothy 1:18 (the Lord grant unto him to find mercy of the Lord in that day); and in how many things he ministered at Ephesus, thou knowest very well.
The verse centers on "mercy", "lord", "grant", "find", "things", "ministered", and "ephesus". It is saying that the verse draws attention to "mercy" and "lord", so its meaning should be read from those terms before moving to application.
The prior verse says "but when he was in Rome he...", giving immediate footing for "mercy" and "lord". In 2 Timothy context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "mercy" and "lord" with trust shaped by these words, not by a vague optimism outside the passage.
