God is unchangeable, always reliable and consistent. “I am the Lord, I change not” (Mal 3:6). He doesn’t change His mind or laws. “Jesus Christ is the same yesterday, today and forever” (Heb 13:8).
We should also be steady, only changing more into His likeness and becoming better people, not emotionally up and down with moods, being influenced by external factors and situations or other people’s responses. Inconsistent and unpredictable people are undependable, undisciplined and have no established patterns. This variableness is because there is no solid foundation or firm convictions.
When we ask, it must be with faith and not doubt which fluctuates because it is influenced by changing conditions. The Bible says such a double-minded person is unstable in all their ways (Jas 1:6-8).
