Passage
And I have a baptism wherewith I am to be baptized. And how am I straitened until it be accomplished?
And I have a baptism wherewith I am to be baptized. And how am I straitened until it be accomplished?
Luke 12:48 But he that knew not and did things worthy of stripes shall be beaten with few stripes. And unto whomsoever much is given, of him much shall be required: and to whom they have committed much, of him they will demand the more.
Luke 12:49 I am come to cast fire on the earth. And what will I, but that it be kindled?
Luke 12:50 And I have a baptism wherewith I am to be baptized. And how am I straitened until it be accomplished?
Luke 12:51 Think ye, that I am come to give peace on earth? I tell you, no; but separation.
Luke 12:52 For there shall be from henceforth five in one house divided: three against two, and two against three.
The verse centers on "baptism", "wherewith", "baptized", "straitened", "until", and "accomplished". It is saying that the verse draws attention to "baptism" and "wherewith", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 49's "I am come to cast fire on..." into verse 51's "Think ye that I am come to...", so "baptism" and "wherewith" belong inside that flow. In Luke context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "baptism" and "wherewith" with trust shaped by these words, not by a vague optimism outside the passage.
