Peter had never preached to the gentiles. In fact, he believed it was against Jewish law to associate with the gentiles. God needed to change Peter’s attitude about this, so during the night Peter had a vision that showed him it was permissible to preach to the gentiles. The Spirit came to Peter and informed him that some men were about to come visit him, and he was to go with them. He went with them and the Lord did great miracles in the lives of gentiles through Peter.
Sometimes we are so bent on our particular belief that the Holy Spirit must do something miraculous to change our paradigm of thought.
I was once asked to attend a conference overseas. At the time finances were such that the very idea was ridiculous to me. The very next day a man I had met only once before informed me of this event and asked if I would come if my expenses were covered. I was dumbfounded! The Lord had sent a messenger to change my paradigm because he knew I didn’t have the faith to think of the possibility. He knew I needed help.
Do you need a paradigm shift in some area of belief? The Lord still intervenes in the lives of His people every day. Don’t be surprised when God begins to change your paradigm by giving you a vision or sending you a messenger of His choosing.
