The Church of Almighty God | What is the nature of the problem of man not knowing the significance of God’s name and not accepting God’s new name? 

Relevant Words of God:

In each period of time, God will begin new work, and in each period, there will be a new beginning among man. If man only abides by the truths that “Jehovah is God” and “Jesus is Christ,” which are truths that only apply to a single age, then man will never keep up with the work of the Holy Spirit, and will forever be incapable of gaining the work of the Holy Spirit. Regardless of how God works, man follows without the slightest doubt, and he follows closely.
