Q. What does the bible say about modern day prophets who God speaks through? And why can we not have any more scriptures according to the Bible?
The Bible was written over a period of 1500 hears by about 40 different writers. They were inspired by the Holy Spirit to write the truths that God wanted revealed.
Everything that man needs to develop his obedience and relationship with God is in the Bible-written by inspiration.
In John’s gospel, he states that we have enough evidence to believe that Jesus is the Christ, the Son of God and that by believing we may have life in his name.
30 Jesus did many other miraculous signs in the presence of his disciples, which are not recorded in this book. 31 But these are written that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.
John 14:25-26 26 But the Counselor, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you. NIV
6 “When the Counselor comes, whom I will send to you from the Father, the Spirit of truth who goes out from the Father, he will testify about me. 27 And you also must testify, for you have been with me from the beginning.
2 Timothy 3:16-4:1
16 All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, 17 so that the man of God may be thoroughly equipped for every good work.
Isaiah, the prophet, says that God’s word will accomplish what He desires for it to accomplish.
11 so is my word that goes out from my mouth: It will not return to me empty, but will accomplish what I desire and achieve the purpose for which I sent it.
Prophets spoke from God.
2 Peter 1:20-2:1
20 Above all, you must understand that no prophecy of Scripture came about by the prophet’s own interpretation. 21 For prophecy never had its origin in the will of man, but men spoke from God as they were carried along by the Holy Spirit.
1:1 In the past God spoke to our forefathers through the prophets at many times and in various ways, 2 but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom he made the universe. 3 The Son is the radiance of God’s glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven.
The writer of Hebrews states that God spoke in former times by prophets, but now speaks through his Son. His Son has sent his word by inspiration and we have it in the form of the Bible.
3 Dear friends, although I was very eager to write to you about the salvation we share, I felt I had to write and urge you to contend for the faith that was once for all entrusted to the saints.
I find that Jude’s statement is very interesting. He says that we are to contend for the faith that was once for all entrusted to the saints. The American Standard Version makes this a little clearer.
3 Beloved, while I was giving all diligence to write unto you of our common salvation, I was constrained to write unto you exhorting you to contend earnestly for the faith which was once for all delivered unto the saints.
In this instance “the faith” represents the body of truth that was delivered.
To answer your question, there are no Biblically inspired prophets who speak for the Lord today. They have no need since we have God’s word.
