This parable will give my opinion some support.
Luke 12:35-40
[35] "Be dressed ready for service and keep your lamps burning, [36] like men waiting for their master to return from a wedding banquet, so that when he comes and knocks they can immediately open the door for him. [37] It will be good for those servants whose master finds them watching when he comes. I tell you the truth, he will dress himself to serve, will have them recline at the table and will come and wait on them. [38] It will be good for those servants whose master finds them ready, even if he comes in the second or third watch of the night. [39] But understand this: If the owner of the house had known at what hour the thief was coming, he would not have let his house be broken into. [40] You also must be ready, because the Son of Man will come at an hour when you do not expect him."
Say in a simple word you are a servant,, and then your Lord told you to do the dishes, clean the house and have his bed ready when He comes home. You do those things..so you are "prepared". Let's say then that the Lord arrived and you done nothing unto the tasks He said,,nor you made an effort to do it at all. Would you expect a salary on it? No. The salary on it is His salvation and living with Him through eternity.
Sorry but this cant be true.
You cannot earn salvation by doing works.
Rom 11:6 And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then is it no more grace: otherwise work is no more work.
Eph 2:8-10 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: (9) Not of works, lest any man should boast. (10) For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
