Whether you feel you hear God speak to you in an audible voice or in your spirit it must line up with revealed revelation of scripture. Have you ever hear the term progressive revelation. I know it is not in the Bible but it means that now that God is speaking to us through His son we understand the previous sections of scripture only in the light of that Higher revelation. Hebrews talks a lot about that. Remember to read the highlighted verse in context of the entire 2 chapters which is about Law verses Grace. Better yet re read all of Galations.
Gal 1:6 I am astonished that you are so quickly deserting the one who called you by the grace of Christ and are turning to a different gospel
Gal 1:7 which is really no gospel at all. Evidently some people are throwing you into confusion and are trying to pervert the gospel of Christ.
Gal 1:8
But even if we or an angel from heaven should preach a gospel other than the one we preached to you, let him be eternally condemned!
Gal 1:9 As we have already said, so now I say again: If anybody is preaching to you a gospel other than what you accepted, let him be eternally condemned!
Gal 1:10 Am I now trying to win the approval of men, or of God? Or am I trying to please men? If I were still trying to please men, I would not be a servant of Christ.
Gal 1:11 I want you to know, brothers, that the gospel I preached is not something that man made up.
Gal 1:12 I did not receive it from any man, nor was I taught it; rather, I received it by revelation from Jesus Christ.
Gal 1:13 For you have heard of my previous way of life in Judaism, how intensely I persecuted the church of God and tried to destroy it.
Gal 1:14 I was advancing in Judaism beyond many Jews of my own age and was extremely zealous for the traditions of my fathers.
Gal 1:15 But when God, who set me apart from birth* and called me by his grace, was pleased
Gal 1:16 to reveal his Son in me so that I might preach him among the Gentiles, I did not consult any man,
Gal 1:17 nor did I go up to Jerusalem to see those who were apostles before I was, but I went immediately into Arabia and later returned to Damascus.
Gal 1:18 Then after three years, I went up to Jerusalem to get acquainted with Peter* and stayed with him fifteen days.
Gal 1:19 I saw none of the other apostlesonly James, the Lord's brother.
Gal 1:20 I assure you before God that what I am writing you is no lie.
Gal 1:21 Later I went to Syria and Cilicia.
Gal 1:22 I was personally unknown to the churches of Judea that are in Christ.
Gal 1:23 They only heard the report: The man who formerly persecuted us is now preaching the faith he once tried to destroy.
Gal 1:24 And they praised God because of me.
Gal 2:1 Fourteen years later I went up again to Jerusalem, this time with Barnabas. I took Titus along also.
Gal 2:2 I went in response to a revelation and set before them the gospel that I preach among the Gentiles. But I did this privately to those who seemed to be leaders, for fear that I was running or had run my race in vain.
Gal 2:3 Yet not even Titus, who was with me, was compelled to be circumcised, even though he was a Greek.
Gal 2:4 This matter arose because some false brothers had infiltrated our ranks to spy on the freedom we have in Christ Jesus and to make us slaves.
Gal 2:5 We did not give in to them for a moment, so that the truth of the gospel might remain with you.
Gal 2:6 As for those who seemed to be importantwhatever they were makes no difference to me; God does not judge by external appearancethose men added nothing to my message.
Gal 2:7 On the contrary, they saw that I had been entrusted with the task of preaching the gospel to the Gentiles,* just as Peter had been to the Jews.*
Gal 2:8 For God, who was at work in the ministry of Peter as an apostle to the Jews, was also at work in my ministry as an apostle to the Gentiles.
Gal 2:9 James, Peter* and John, those reputed to be pillars, gave me and Barnabas the right hand of fellowship when they recognized the grace given to me. They agreed that we should go to the Gentiles, and they to the Jews.
Gal 2:10 All they asked was that we should continue to remember the poor, the very thing I was eager to do.
Gal 2:11 When Peter came to Antioch, I opposed him to his face, because he was clearly in the wrong.
Gal 2:12 Before certain men came from James, he used to eat with the Gentiles. But when they arrived, he began to draw back and separate himself from the Gentiles because he was afraid of those who belonged to the circumcision group.
Gal 2:13 The other Jews joined him in his hypocrisy, so that by their hypocrisy even Barnabas was led astray.
Gal 2:14 When I saw that they were not acting in line with the truth of the gospel, I said to Peter in front of them all, You are a Jew, yet you live like a Gentile and not like a Jew. How is it, then, that you force Gentiles to follow Jewish customs?
Gal 2:15 We who are Jews by birth and not Gentile sinners
Gal 2:16 know that a man is not justified by observing the law, but by faith in Jesus Christ. So we, too, have put our faith in Christ Jesus that we may be justified by faith in Christ and not by observing the law, because by observing the law no one will be justified.
Gal 2:17 If, while we seek to be justified in Christ, it becomes evident that we ourselves are sinners, does that mean that Christ promotes sin? Absolutely not!
Gal 2:18 If I rebuild what I destroyed, I prove that I am a lawbreaker.
Gal 2:19 For through the law I died to the law so that I might live for God.
Gal 2:20 I have been crucified with Christ and I no longer live, but Christ lives in me. The life I live in the body, I live by faith in the Son of God, who loved me and gave himself for me.
Gal 2:21 I do not set aside the grace of God, for if righteousness could be gained through the law, Christ died for nothing!*
