Passage
And the word of the Lord came to Samuel,
And the word of the Lord came to Samuel,
1 Samuel 15:8 And he took Agag, the king of Amalec, alive: but all the common people he slew with the edge of the sword.
1 Samuel 15:9 And Saul and the people spared Agag, and the best of the flocks of sheep, and of the herds, and the garments and the rams, and all that was beautiful, and would not destroy them: but every thing that was vile, and good for nothing, that they destroyed.
1 Samuel 15:10 And the word of the Lord came to Samuel,
1 Samuel 15:11 It repenteth me that I have made Saul king: for he hath forsaken me, and hath not executed my commandments. And Samuel was grieved, and he cried unto the Lord all night.
1 Samuel 15:12 And when Samuel rose early, to go to Saul in the morning, it was told Samuel that Saul was come to Carmel, and had erected for himself a triumphant arch, and returning had passed on, and gone down to Galgal. And Samuel came to Saul, and Saul was offering a holocaust to the Lord, out of the choicest of the spoils, which he had brought from Amalec.
The verse centers on "word", "lord", "came", and "samuel". It is saying that the verse draws attention to "word" and "lord", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 9's "And Saul and the people spared Agag..." into verse 11's "It repenteth me that I have made...", so "word" and "lord" belong inside that flow. In 1 Samuel context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "word" and "lord" with trust shaped by these words, not by a vague optimism outside the passage.
