What does the story of Pharaoh's magicians teach us?

The confrontation between Aaron's miracle and the magicians' ability to mimic it in Exodus 7 highlights a crucial lesson about the limitations of earthly authority and the undeniable supremacy of God. While the magicians were able to transform their rods into serpents, the power of Aaron's rod, which swallowed theirs, signified that God's power cannot be overshadowed or replicated by false gods and spirits. This act not only serves to illustrate God’s superior authority but also signals the futility of trusting in idols or human wisdom when standing against the might of the true God. Further, it reinforces the Reformed teaching that true knowledge and power come only through God’s revelation.
