Why is the lamb important symbol of Easter?

Answer 1

maybe its their white (usually) wooly coats, or the fact that they're probably one of the earliest tamed/domesticated animals, and are generally easy to herd and look after since they are not aggressive by nature.

it is the symbol of purity because in the time before jesus they would weekly sacrifice an unblemished lamb with no defect to substitute for the sins of the people and when jesus came to earth as a man he came as the lame of god that would bear the sins of man (and women) forever

Answer 2

Easter is the time the death burial and resurrection of Jesus is remembered.

As written in The Bible, a lamb is a sacrifice for sin.

Jesus came as the lamb of God:

Joh 1:29 The next day John saw Jesus coming toward him, and said, "Behold! The Lamb of God who takes away the sin of the world!

to die as a suitable sacrifice for all who believe
