Easter (The Lamb)

What is the connection between Easter and a lamb, to me as a Christian it us very significant in The Bible it says that Christ is (The Lamb of God)
When Jesus is called the Lamb of God in John 1:29 and John 1:36, it is referring to Him as the perfect and ultimate sacrifice for sin. In order to understand who Christ was and what He did, we must begin with the Old Testament, which contains prophecies concerning the coming of Christ as a “guilt offering” (Isaiah 53:10). In fact, the whole sacrificial system established by God in the Old Testament set the stage for the coming of Jesus Christ, who is the perfect sacrifice God would provide as atonement for the sins of His people (Romans 8:3; Hebrews 10).
So to me where a lamb was used as a sacrifice Christ was a sacrifice for us.
As it says in John: 3 16 For God so loved the world that He gave His only begotten Son that whosoever believth in Him would niot perish but have everlasting life.
To me these words are so vital and true (CHRIST HAS RISEN).
