The correct understanding from biblical writings is that they are certain beyond every doubt: God does not change. In scripture, God is often described as immutable, meaning that His nature, character, and promises do not change over time. This belief is reflected in various passages, such as Malachi 3:6, which states, "For I the Lord do not change," and James 1:17, which speaks of God as "the Father of lights, with whom there is no variation or shadow due to change." While there may be discussions about God's actions in relation to humanity, His fundamental nature is presented as constant.
As we read what the biblical writers wrote about the possibility God might change, we learn
they are convinced that God is mutable
they are certain beyond every doubt: God does not change
they are uncertain about God’s immutability
they are split regarding the possibility God might change
