Whatever is good and perfect is a gift coming down to us from God our Father, who created all the lights in the heavens. He never changes or casts a shifting shadow.
When prayers are answered we are receiving a perfect gift from God. We should then be good stewards of what God has given, not squandering our opportunities to glorify Him. When we honor our Father in heaven by serving Him wholeheartedly, the outside world can get a glimpse of Christ that may spark their curiosity and lead them into a relationship with God.
