Malachi 4:5-6 is a two part prophecy; 1. John the Baptist turned the hearts of the fathers to the children, that is, made people’s hearts ready to receive Jesus Christ, turning them from the law to the gospel. 2. William Branham turned the hearts of the children to their fathers, that is, restored the end time believers back to the original faith. 

Restored the truth about the Godhead. 

The truth of the Godhead was understood by the apostles and the next generations of Christians, but in time this understanding was lost and debates between Christians began rage over the nature of Father, Son and Spirit, resulting in many varying understandings. Even the Trinity doctrine is disputed as to the meaning of God as Father, Son and Spirit. Brother Branham rejected both extreme Trinitarianism and Jesus only (Modalistic Monarchian) doctrines. He taught a viewpoint that is very much the same as the apologists of the 2nd and 3rd Century. There are many theologians in the 20th and 21st Century that have acknowledged that persons is not an adequate expression for the distinctions within God. Trinitarian Theologians Karl Barth and Eberhard Jungel preferred to use the terms “modes of being” in contrast to persons. John S. Whale regarded the Trinity as a “personal unity existing eternally in three eternal modes or functions.”[J S Whale, Christian Doctrine, pg 116]

Theologian GHW Lampe described the social Trinity as “a…unity of human persons in a social ‘Trinity’ in which three persons in the full psychological sense of persons are bound together in mutual love, implies the existence of three divine consciousness, in other words-three Gods.”1 Keith Ward a philosopher and theologian states, “To admit many centres of awareness in God would split the Divine unacceptably, entailing that none of them are omniscient or omnipotent. The view is indistinguishable from a more robust polytheism, and must be rejected by thoroughgoing monotheists, such as Christians are supposed to be.”[Keith Ward, Rational Theology and the Creativity of God, pg 863.]

Brother Branham likened Father, Son and Spirit to the human body, soul and spirit. One person with three distinct aspects that make him a man. One God with three different aspects or attributes that make him God. 

Restored the truth of modesty. 

Brother Branham taught that women should dress modestly, avoid the use of make-up and have long hair based upon the Scriptures. He also taught that a woman could have the gifts of the Spirit in her life and that she was the pastor of her home, leading the children, but that she was not called to be in a position of leadership, pastoring or teaching before the church. (1 Timothy 2:12) In the beginning God took Eve from Adam’s side, so she was a part of him and she was his equal.

Restored the truth of the Name in Baptism.

Matthew 28:19 states that baptism should be done in the NAME of the Father, Son and Spirit. Acts 2:38 and every other instance in the book of Acts baptism was done in the name of the Lord Jesus Christ. The ONE NAME of Father, Son and Spirit is the Lord Jesus Christ. Jesus came in his Father’s Name, John 5:43, and the Holy Spirit is sent in the name of Jesus, John 14:26. James Hastings, noted Bible scholar writes, “It has been customary to trace the institution of the practice to the Words of Christ in Matthew 28:19, but the authenticity of this passage has been challenged on historical as well as textural grounds. It must be acknowledged that the formula of the threefold name, which is here enjoined, does not appear to have been used by the primitive church, which so far as our information goes, baptized ‘in’ or ‘into’ the Name of Jesus, or Jesus Christ, or the Lord Jesus, without any reference to the Father or the Spirit” (Dictionary of the Bible, p. 88) William Phillips Hall wrote, In this very ancient version (Syriac Peschito Version) which is believed by good authorities (Gwilliam, Boners, and others) to represent a text much older that of the Greek manuscript from which our English Old Testament was largely derived, ‘The Name of the Lord Jesus Messiah or Christ’ appears in all four readings given (Acts 2:38; 8:16; 10:48; 19:5)” (A Remarkable Discovery, p. 70).

Restored the truth about hell. 

He is often identified with Jehovah’s Witness and Seventh-Day Adventist doctrine in this regards, but his teaching was quite different. In fact, brother Branham’s view was very similar to that of noted British Theologian, John Stott. He believed in a place of torment after death, but that it resulted in ultimate extinction of being. As John Stott wrote, “The vocabulary of ‘destruction’ is often used in relation to the final state of perdition. The commonest Greek words are the verb apollumi (to destroy) and the noun apòleia (destruction)…Jesus himself told us not to be afraid of those who kill the body and cannot kill the soul. ‘Rather,’ he continued, ‘be afraid of the One [God] who can destroy both soul and body in hell’ (Mt 10:28); cf. Jas 4:12). If to kill is to deprive the body of life, hell would seem to be the deprivation of both physical and spiritual life, that is, an extinction of being.”[David L. Edwards and John Stott: Evangelical essentials: a liberal-evangelical dialogue]

Revealed the hidden mystery of what happened in the garden. 

It wasn’t apples that caused Eve to realize she was naked. And it wasn’t eating a literal fruit that caused the woman to receive increased pain and conceptions in child bearing. God commanded Adam and Eve to multiply and replenish the earth, he also ordained that all seed should bring forth of its kind. The Serpent, was not a snake, but an upright animal, that could speak and even reason with Eve. If Satan miraculously gave the Serpent the ability to speak this would be a shock to Eve and cause a revulsion to her. Instead this was a normal occurrence for her to speak with the Serpent. He was not made in the image and likeness of God and yet he so closely related to the human race that it would be likened to the difference between the bison and the cow. “Such is the way of an adulterous woman; she eateth, and wipeth her mouth, and saith, I have done no wickedness.” Proverbs 30:20. Eve ate of the fruit of the tree, the serpent beguiled her, she became pregnant and brought forth Cain, who was of the wicked one. 1 John 3:12. Adam knew her as well, taking back his wife, after she became the partner of another man, she also became pregnant by Adam. As a result God cursed Eve and gave her pain in childbearing. The ground was cursed for the sake of Adam, the unchanging God, who’s Word is written in heaven before the world began, as taught in Deuteronomy 24:1-4.
