After being baptized with the Holy Spirit, and then comes to know Jesus voice, is told, by Jesus (Holy Spirit): not to kill for any reason, not to store up for their future, not to call any man father, that they cant be a disciple of Jesus unless they give up all their possessions, and that a Christian is dead to sin?
The above points can be obtained even without being Baptized with the Holy Spirit. One does not need a special mysterious voice to tell them. Every sincere Bible-student knows them as they can be very easily found in the Bible.
Exodus 20:13 - Thou shalt not kill.
Matthew 6:19 - Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and where thieves break through and steal:
Matthew 23:9 - And call no man your father upon the earth: for one is your Father, which is in heaven.
Luke 14:33 - So likewise, whosoever he be of you that forsaketh not all that he hath, he cannot be my disciple.
Romans 6:2 - God forbid. How shall we, that are dead to sin, live any longer therein?
What if what the Holy Spirit tells you are the Words of God, the Bible, and what the Church tells you doesnt agree with the Word of God?
Different Churches interpret the Bible in different ways and therefore have different doctrines but they all do come under one banner i.e Christianity. This does not mean that what the Church tells you does not agree with the Bible. If one takes a literal interpretation of the Bible he understands the Bible verses in a different way than another who takes the spiritual meaning. It takes a few years to properly understand the Bible in a spiritual way. There are matured Christians who have the experience of being baptized in the Holy Spirit and who have in-depth understanding of the Bible coupled with their practical experience in life. So, they speak in a practical way which may appear to disagree with the word of God especially for those who are new to the Bible or for those who have not yet grasped the meaning or the context in which the Preacher spoke.
I first introduced this thread in the Catholic section, but found it wasnt the proper part of this forum to discuss this subject. I thought it was a situation that many Catholics found stressful, but then I thought all Christians might have to struggle with this question. I was a Catholic and had to personally struggle with those very same questions.
I hope a few of your questions are answered now.
