An idea on how to transition a conversation to share the gospel:
Use the fact that people have decorated with eggs or that they are taking their kids on an egg hunt...Tell them how easy it is for you to forget the meaning of the eggs. Then go on to explain that the eggs symbolize new life. You can then explain about being born again, about Jesus giving us new life, and unpack the gospel in a way that makes sense to who you are talking to, and bring Easter into a new light for that person.
Eggs and resurrection. They go together. Our new life is because of what Jesus did on the cross and that he rose from the dead. O, what an amazing truth!
