The Bible does not "bring arguments".
But rather, Its the inability of a religious person to rightly divide the word of God, that causes the STRIFE.
or,
its a badly instructed believer, who has been fed "doctrines of devils" and has become their theology, that causes the STRIFE.
"Strife" is devil led confusion regarding bible verses or bible doctrine.
Now, to answer your question...
Its very simple, once you see it.... Charlie24.
Let me show it to you , the answer, from Acts 10....
First, you recall that Peter, in Acts 2, led 3000 into the body of Christ.
He spoke with the Gift of Tongues, to Jews, during Pentecost, as "jews require a sign", and "tongues are FOR a SIGN.."
1 Corinthians 1:22.......1 Corinthians 14:22
So, Peter has the apostolic Jewish "SIGN(s) of an Jewish Apostle"....
2 Corinthians 12:12
However, what He didn't have until Acts 15, was the revelation of Paul's ""Gospel of the Grace of God."""
Peter began to understand it, somewhat, 10 yrs after the Crucifixion, when God gave Peter a vision, in Acts 10, and explained to Peter that GENTILES could be saved.......as Peter had no idea even as late as Acts 10, which is about a Decade after Christ has ascended back into Heaven.
So, Peter was preaching the " water baptism of John", as that is what religious Jews preached in the OLD TESTAMENT.
Its all he KNEW to preach being an Old Testament JEW.
Now, i just showed you, that the same Apostle who led 3000 to Christ, didn't know during Pentecost, or even nearly 10 yrs later, that GENTILES could be saved.
So, what Peter didn't KNOW, .. He can't Preach or Teach.
Understand?
So, here is a key to understanding some verses ....
Its this......"not all the Apostles had the same KNOWLEDGE or REVELATION at the SAME TIME".
So, when an apostle does not PREACH = Paul's Gospel, of "faith is counted as righteousness", and "Justification by faith, without WORKs".. and '"Abraham is the father of our FAITH".......then that apostle has Peter's issue, that Peter had in Act's 10.
He does not know all the revelation yet., regarding PAUL's GOSPEL being THE Gospel.
And this is why the Apostles met in Acts 15.
It was a meeting that allowed them all to "catch up" and get Paul's Revelation.
Reader,
There are no contradictions in the Bible.
What you find is that the bible is a historical document of the TIME its talking about, and regarding each Apostle, at that TIME, is talking about them, and showing you what they KNEW at that time.
What they dont KNOW yet, they can't preach or teach, yet.
The Bible is completely HONEST...>IT does not try to create false similitude, when there isn't any.
This is why the Gospel's dont have the same STORY< exactly..... as its 4 people giving THEIR Eyewitness of Christ and His ministry.
Each has a few different observations, a few different points of view, as that is the BIBLE being HONEST, as 4 people watching the same eye-witnessed event will have the same BASIC Truth, but each will have a unique point of view, regarding their observation of the exact same EVENT.
The Bible is TRUE.
Trust it.
