Romans 14:7-9 (ESV):
7 For none of us lives to himself, and none of us dies to himself. 8 For if we live, we live to the Lord, and if we die, we die to the Lord. So then, whether we live or whether we die, we are the Lord's. 9 For to this end Christ died and lived again, that he might be Lord both of the dead and of the living.
I see echoes of Luke 20:37-38 & John 11:25-26 in the above passage:
37 But that the dead are raised, even Moses showed, in the passage about the bush, where he calls the Lord the God of Abraham and the God of Isaac and the God of Jacob. 38 Now he is not God of the dead, but of the living, for all live to him.”
[Luke 20:37-38 ESV]
25 Jesus said to her, “I am the resurrection and the life. Whoever believes in me, though he die, yet shall he live, 26 and everyone who lives and believes in me shall never die. Do you believe this?”
[John 11:25-26 ESV]
Question: What does it mean that Jesus is "Lord both of the dead and of the living"? Does it mean that the Lord-servant relationship between Jesus and the believer continues after death? Does it mean something else?
