Paul Williams, a convert to Islam, who claims to be a former Christian, which means he is an apostate (see Hebrews 3:12) wrote this:
The evidence is simple: the New Testament does not claim to be Revelation from God. The onus is on Christians to prove that it is.
see the discussion here.
For I have given them the words that You [The Father] gave Me, and they have received them and have come to know in truth that I came from you; and they have believed that you sent me.
“Your Word is Truth”
The Words of the Father were given to Jesus the Son and He gave them to the apostles and sent the Holy Spirit who would lead them into all the truth and bring to their remembrance all that He taught.
John 14:26 and John 16:12-13
Eventually, they wrote down their preaching, all by the end of 1st century.
Mark for Peter; Peter is eyewitness
Luke as traveling companion of the apostle Paul
The Lord brings Paul into that apostolic band of revelation – Acts 9, Acts 15 (Peter, James, and Paul all agree on the essentials of gospel message), Acts 22, 26; I Corinthians 9, I Cor. 15; Galatians 1-2 – visits Peter, John, James and they affirm his gospel message as the same as theirs.
John – eyewitness, disciple
Matthew – eyewitness, disciple
1 Thessalonians 2:13
13 And we also thank God constantly for this, that when you received the word of God, which you heard from us, you accepted it not as the word of men but as what it really is, the word of God, which is at work in you believers.
2 Thessalonians 2:13-15
13 But we ought always to give thanks to God for you, brothers beloved by the Lord, because God chose you as the first fruits to be saved, through sanctification by the Spirit and belief in the truth.
14 To this he called you through our gospel, so that you may obtain the glory of our Lord Jesus Christ.
15 So then, brothers, stand firm and hold to the traditions that you were taught by us, eitherby our spoken word or by our letter.
But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed. 9 As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be accursed.
“so now I say again” = I am saying this through my writing this letter of Galatians.
1 Corinthians 2:10-13
10 these things God has revealed to us through the Spirit. For the Spirit searches everything, even the depths of God.
11 For who knows a person’s thoughts except the spirit of that person, which is in him? So also no one comprehends the thoughts of God except the Spirit of God.
12 Now we have received not the spirit of the world, but the Spirit who is from God, that we might understand the things freely given us by God.
13 And we impart this in words not taught by human wisdom but taught by the Spirit, interpreting spiritual truths to those who are spiritual.
1 Timothy 5:18
For the Scripture says, “You shall not muzzle an ox when it treads out the grain,” [quote from Torah, Deuteronomy 25:4]
and, “The laborer deserves his wages.” [quote from Gospels, Matthew 10:10 and Luke 10:7; also in 1 Corinthians 9:14]
2 Timothy 3:15 – the sacred writings you learned as a child” = OT / Tanakh
2 Timothy 3:16 – “All Scripture is God-breathed” = expands to NT Gospel and books
In principle, includes even books not written yet ( 2 Timothy written in 67 AD, before Paul was executed by Nero)
Also 2 Peter 3:16 claims all of Paul’s letters are Scripture, on the same level as OT (with 2 Peter 1:19-21). So the New Testament does claim to be revelation from God.
It does not matter if you think 2 Peter was written later than 67 AD and not by Peter; it is still part of the New Testament and claims that it is revelation from God.
the book of Revelation also claims this for itself – Revelation 22:18.
Jude 1:17 – remember the words that were spoken to you beforehand by the apostles of our Lord Jesus Christ”
The way to remember them was to read them when they wrote them down.
2 Peter 1:12-18 – I am being diligent by writing this letter to you before I die so that you will have something to read and remember the truths you have been taught.
2 Peter 3:1 – this is the second letter I am writing to you by which I am stirring up your sincere minds in order to remember the truths you have been taught
Paul Williams could not argue with those verses, so he then asked,
And what about Acts/Luke do you claim Luke thought he was writing God’s Revelation?
Luke 1:4 – “in order that you may know the certainty of what you have been taught” = I am writing this down, so you will know the certainty of the truth of the gospel revelation that you were taught, which is what all those other verses above was about. Luke confirms Paul’s preaching as God’s revelation; and Acts chapter 1 shows he is writing about “all that Jesus began to do and teach”, means Luke is writing about what Jesus continues to do through His apostles and His Church. The Greek verb tense here is very important and clear that he is continuing to show what the Holy Spirit does through the apostles and the church, the Holy Spirit who was sent by the Father and the Son together – Acts 2:33-36.
