Can I rephrase your question....
I'm professing salvation but am I saved or will I make it to heaven, if I don't know God's voice nor do I communicate with Him like I know I should?
You've received several answers, but how do you know who's speaking truth and who's not? Do you really want to rely on other people to answer an eternal life/death question such as this? I personally, would want to know for myself and not take anyone's word for it. The Bible says, "study to shew theyself approved unto God, a workman that needeth not to be ashamed, rightly dividng the word of truth." (2 Tim 2:15)
Consider this...
"Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him. He that loveth me not keepeth not my sayings: and the word which ye hear is not mine, but the Father's which sent me." (John 23-24)
We are told to love God with all of our hearts, mind, and souls and if we love Him we will keep His words, but in order to keep His words we must know what His word is, right?
In this day in time, you really need to know God's voice for yourself and the only way to do that is to have a relationship with Him through prayer, studying His word, and even by the Holyghost-(who is our teacher).
Please don't be one of these...
21Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
22Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? 23And then will I profess unto them, I never knew you: depart from me, ye that work iniquity (Matt 7:21-23)
