When you fulfil your obligation to pay for your house do you still intend to keep paying?
Jesus clearly answered your question: Matthew 7:21-23 - 21”Not everyone who says to Me, ‘Lord, Lord,’ will enter the kingdom of heaven, but he who does the will of My Father who is in heaven will enter. 22”Many will say to Me on that day, ‘Lord, Lord, did we not prophesy in Your name, and in Your name cast out demons, and in Your name perform many miracles?’ 23”And then I will declare to them, ‘I never knew you; DEPART FROM ME, YOU WHO PRACTICE LAWLESSNESS.’
This is because a real Christian (not in name only) is a new creation. “Therefore, if anyone is in Christ, he is a new creation; the old has gone, the new has come!” (2 Corinthians 5:17). The Bible declares that a true Christian will not live a state of continual, unrepentant sin (1 John 3:6). The Bible also says that anyone who departs the faith is demonstrating that he was never truly a Christian (1 John 2:19). He may have been religious, he may have put on a good show, but he was never born again by the power of God. “By their fruit you will recognize them” (Matthew 7:16).
Wha???
When you keep the speed limit once, does that mean you never have to keep it again?
