Luke 12:39-48 and Romans 6:12-18

Luke 12:39-48
39 But know this: that if the father of the family knew at what hour the thief would arrive, he would certainly stand watch, and he would not permit his house to be broken into.
40 You also must be prepared. For the Son of man will return at an hour that you will not realize."
41 Then Peter said to him, "Lord, are you telling this parable to us, or also to everyone?"
42 So the Lord said: "Who do you think is the faithful and prudent steward, whom his Lord has appointed over his family, in order to give them their measure of wheat in due time?
43 Blessed is that servant if, when his Lord will return, he will find him acting in this manner.
44 Truly I say to you, that he will appoint him over all that he possesses.
45 But if that servant will have said in his heart, 'My Lord has made a delay in his return,' and if he has begun to strike the men and women servants, and to eat and drink, and to be inebriated,
46 then the Lord of that servant will return on a day which he hoped not, and at an hour which he knew not. And he will separate him, and he will place his portion with that of the unfaithful.
47 And that servant, who knew the will of his Lord, and who did not prepare and did not act according to his will, will be beaten many times over.
48 Yet he who did not know, and who acted in a way that deserves a beating, will be beaten fewer times. So then, of all to whom much has been given, much will be required. And of those to whom much has been entrusted, even more will be asked.
Romans 6:12-18
12 Therefore, let not sin reign in your mortal body, such that you would obey its desires.
13 Nor should you offer the parts of your body as instruments of iniquity for sin. Instead, offer yourselves to God, as if you were living after death, and offer the parts of your body as instruments of justice for God.
14 For sin should not have dominion over you. For you are not under the law, but under grace.
15 What is next? Should we sin because we are not under the law, but under grace? Let it not be so!
16 Do you not know to whom you are offering yourselves as servants under obedience? You are the servants of whomever you obey: whether of sin, unto death, or of obedience, unto justice.
17 But thanks be to God that, though you used to be the servants of sin, now you have been obedient from the heart to the very form of the doctrine into which you have been received.
18 And having been freed from sin, we have become servants of justice.
