Now while Peter was inwardly perplexed as to what the vision that he had seen might mean, behold, the men who were sent by Cornelius, having made inquiry for Simon's house, stood at the gate and called out to ask whether Simon who was called Peter was lodging there. And while Peter was pondering the vision, the Spirit said to him, “Behold, three men are looking for you. Rise and go down and accompany them without hesitation, for I have sent them.” And Peter went down to the men and said, “I am the one you are looking for. What is the reason for your coming?” Acts 10:17-21
Peter was perplexed by the vision and instructions he received from the Holy Spirit. Of course He was! This revelation was contrary, not only to what Peter knew and believed, but to the Old Testament dietary laws! Two considerations:
This was a special time of transition. Jesus had established a New Covenant, which in many ways superseded the Old Covenant. The New Covenant did not obliterate the Old Covenant. The Ten Commandments are still the Ten Commandments, but the New Covenant does lay aside both the Jewish civil caw, and the ceremonial law (including the dietary laws).
Peter was a person in a special position. As an Apostle, Peter did receive special revelation—He wrote two books in the New Testament!
My point? While God spoke to the Apostles during those times of transition, the way He speaks to us today is through His Word. I know you know it, but let me say again, do not trust in anything about God or supposedly from God unless it check out 100% with God’s Word. I wish it were not so, but sadly, people who should know better routinely claim “God told me…” If it is not clearly from His Word, it is not from Him.
