As Philip began to preach to the Samaritans, he was entering a kingdom that was controlled by Satan. To deceive the Samaritans, the Devil had empowered a man named Simon to perform magic so that the people would follow him rather than God. Simon may not have realized the source of his magic, but claimed to be someone great and received the praise of the people. Philip boldly began to teach the Word and demonstrate true miracles from God which showed the people who the true God was, and many were converted and baptized. Even Simon believed, at least superficially. So by the power of Christ, Satan’s grip on the region was broken and the Gospel went forth.
We draw parallels to our own day from this account, seeing the spiritual warfare that we are engaged in and that we have weapons to the demolishing of Satan’s strongholds. We are encouraged to be as bold as Philip in proclaiming the Truth, and to seek God in prayer for the fruit of saved souls.
