This follows along with the post about Paul.
Can we trust the word from the other disciples?
Or could they have been deceived by Paul?
This might seem strange to most believers to question the disciples but that is what Satan wants us to do. “Hath God Said?” So Satan comes along and encourages others to question the disciples and the books in the NT written by them and Paul. Satan doesn’t mind convincing you that you are doing just fine because you are willing to follow the Words of God, it is just the disciples or Paul that you question. But that is very dangerous territory.
See who wrote the Words of God for us?
Did God write down the Words of God?
Two instances that I know are recorded that the Lord physically wrote.
Exodus 31:18 And he gave to Moses, when he had finished speaking with him on Mount Sinai, the two tablets of the testimony, tablets of stone, written with the finger of God. ESV
John 8:8 And once more he bent down and wrote on the ground. ESV
Beyond that every word of God was written by a man through the Holy Spirit. So if we start throwing out, nullifying or belittling the writings of the disciples, we are tampering with Scripture ourselves.
How can we then know what God has said if we cannot trust the words written by Paul, the disciples or the prophets?
