When Peter shared the Gospel with Cornelius -- a Gentile -- it served as an example that sometimes, God will push us outside our comfort zones and cause us to break traditions for the ultimate goal of reaching others. It's important to listen for the voice of God so that we're not venturing out and doing things on our own. The people He calls us to reach and the places He calls us to go might stretch us personally, but every person is in need of a Savior, and it's our responsibility to share the Good News.
