Can I be conformed to Christ and still hang on to old habits?

Luke 18:21-23The man replied, “I’ve obeyed all these commandments since I was young.” When Jesus heard his answer, he said, “There is still one thing you haven’t done. Sell all your possessions and give the money to the poor, and you will have treasure in heaven. Then come, follow me.” But when the man heard this he became very sad, for he was very rich.

In this parable, Jesus shows that it is very difficult to let go of the things of this world that distract you from following him. Conforming to his standards is hard work and requires much from you, but it brings freedom from being enslaved to sin and eternal rewards far greater than you could imagine.
