Again, one does not need to "ask" the Holy Spirit if Gods Word is true? It is and it is evident that a man must be "born-again".
Also Paul and his epistles are the source of all sound doctrine and the truth of the gospel. All other scripture must yield to that which he taught and must be understood in the light of the revelation of Gods grace and the gospel of grace given through this one man. Christ is not "a witness" He is the focus of all that Paul taught and is the very Image of God. All truth being "a witness" to Him and His Image.
Ro 2:16 In the day when God shall judge the secrets of men by Jesus Christ
according to my gospel.
Ga 1:1 ¶
Paul, an apostle, (not of men, neither by man, but by Jesus Christ, and God the Father, who raised him from the dead
2 And all the brethren which are with me, unto the churches of Galatia:
3 Grace be to you and peace from God the Father, and from our Lord Jesus Christ,
4 Who gave himself for our sins, that he might deliver us from this present evil world, according to the will of God and our Father:
5 To whom be glory for ever and ever. Amen.
6 ¶ I marvel that ye are
so soon removed from him that called you into the grace of Christ unto another gospel:
7 Which is not another; but there be some that trouble you, and would
pervert the gospel of Christ.
8
But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed.
9 As we said before, so say I now again, If any man preach
any other gospel unto you than that ye have received, let him be accursed.
And again you might not like the answer, when I ask the Holy Spirit to judge the truth of some of the things you have tried to affirm, I allow that you may have some doctrines that are in error and some doctrines that are in agreement with the truth, which most believers are in the process of growth. But this doctrine that seeks to reject the "rebirth" in Christ, does not allow me to have much confidence that you are able to judge the voice of truth as you should?
