All of the Father‘s faculties were fully mobilized before His creative act.
Moreover, the intellects of the Holy Spirit and the Son were uplifted before creation.
Regarding the Holy Spirit, His power was awakened immediately after creation; and His will, just before the giving of the first grace to the angels.
Regarding the Son, there are 5 major events of His life: conception, birth, baptism, death, and resurrection.
Thus, Christ’s power was given to Him at conception; accepted at birth; charity in the will was given at baptism; tested at death; accepted at resurrection.
