What did Yokhanan (a.k.a. John the Baptist) mean when he told his disciples that Yeshua was “the Lamb of God, Who takes away the sins of the world”? What does it have to do with Passover and the day the Passover lamb is selected?
Passover is an annual memorial of the LORD’s deliverance of Israel from bondage, but the focus is the lamb and Who the lamb represents: He Who was pierced to give us freedom and a new life in communion with God.
Yeshua (Jesus) said His “time” had come at that Passover He died as the Lamb of God. Yet, likely there was an “appointed time” for His conception and birth that was in line with “appointments” the LORD already had established.
Why are we to teach our children about plagues, blood, and death of animals and people 3,500 years ago?
God’s ways may be mysterious, but when He lays out patterns and times important historical events accordingly, He is inviting us to learn more about what He is doing. There’s a “new beginning” lesson in the spring festivals of the LORD on Yeshua (Jesus).
Studying the statutes, judgments and commands of the Lord is not limited to the “four questions” during the Passover seder (program). We are to listen and obey God on a daily basis. We also learn more when we are called to teach others.
At the time of the Exodus, YHWH (God’s personal name in Hebrew, often translated as “the LORD”) told the people of Israel to have a “lamb for a household” (Exodus 12:3). Usually 10 people could manage to consume a whole lamb. Smaller groups joined together to form a chaverim, Hebrew for “a group of friends,” and that formed a mishpokhah, “a family group.” Paul talks about believers being the “household of God” (1st Timothy 3:15) because there is a “lamb for the household.”
