"And he reported to us how he had seen the angel standing in his house, and saying, 'Send to Joppa and have Simon, who is also called Peter, brought here; and he will speak words to you by which you will be saved, you and all your household.'  And as I began to speak, the Holy Spirit fell upon them just as He did upon as at the beginning.  And I remembered the word of the Lord, how He used to say, 'John Baptized with water, but you will be baptized with the Holy Spirit.'  Therefore if God gave to them the same gift as He gave to us also after believing in the Lord Jesus Christ, who was I that I could stand in God's way?  When they heard this, they quieted down and glorified God, saying, 'Well done, God has granted to the Gentiles also the repentance that leads to life."

Believing is a tricky business.

Peter is telling this story because the believers in Jerusalem did not believe that a Gentile could have the capacity to believe in God.  This is a long way from the covenant God originally gave to Abram:  "The world will be blessed through you," turned into, "Only you will be blessed."

Happens to all of us.  We decide we need love.  More love.  All the love.

Theologians call it jealousy.  We are all victims.

And in Peter's speech, and the consequential response, we see the cure for common jealousy.

The people from Jerusalem listened to the Caesarean's story.  Then they responded with rejoicing about God's power.

Try this:  Listen to someone else talk about their life.  You will soon find reason to rejoice instead of covet.
