First, you must know that your sins were forgiven at the cross. However, each of us desires to live a holier life, free from the sin in our life. We cannot ever achieve perfection in this life, but the scripture tells us to strive for it.
So, is your dilemea that you are afraid of the consequences of surrendering areas of your life?
Or is it that you are afraid of the cosequences if you don't?
These two questions are very different from each other.
I will ask you another question, Jesus said, "If you love me, you will keep my commands." If you do not surrender these areas of your life to Him, how do you know that you really love Him? It is by our surrender to Christ daily that we know we are His. Even Paul says "I die daily".
Now, when you do surrender an area of your life, a like, a dislike, whatever it may be, you must remember that you are relying on God, not a god, the God, of the whole universe, and if He was able to create the entire universe so that it could function together in harmony, don't you think He can direct your life?
[b]He is more than able.[/b]
And He does not make you pay for all the things you did wrong before you became a Christian.
I hope this helps, if you want to talk more about it, just send me a message, and we can talk about it that way.
