It is simply not possible for God to contradict His own word in Isaiah 52:6, where His name is yet to be given in the future. Therefore, the names mentioned in Exodus and Psalms are merely the result of a human understanding that regarded them as God’s name.
For according to Isaiah 52:6, God’s name is a secret that He reveals only to His chosen ones who have overcome
REVELATION 2:17
17 He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh will I give to eat of the hidden manna, and will give him a white stone, and in the stone a new name written, which no man knoweth saving he that receiveth it.
What is found in Exodus and Psalms, however, is public and not secret, because everyone who reads the Holy Scriptures can know it. Therefore, it cannot be God’s name because not everyone has overcome.
May I ask you something: Have you been given the white stone from God, on which His name is written?
