I didn't say that any one in particular should be offended. I am offended as a Christian, which Obama claims to be as well. The Passover is about 2 events in history.
1) the Passover for Jews is about the calling out of the Israelites from slavery in Egypt to worship their God, the LORD, the one true God. This was done when the angel of death killed the first born of all those in Egypt who did not have the blood of the paschal lamb upon their doors.
2) The Passover in Egypt is the precursor and foreshadowing of the coming of Christ. John said of Jesus, 'behold the lamb of God who takes away the sins of the world.' The passover is ultimately about freedom to worship the one true God. Not just in freedom from slavery in Egypt, but in freedom from the slavery of sin.
Obama takes a story about the Messiah, and compares it to political struggle in Arab countries. Obama takes the story of the Saviour of the world, God's only Son, and says it is essentially the same as Muslims in Arab countries fighting for political power.
Maybe some on here aren't offended. If you are not a professing Christian I can see where you are not offended. If you are a Christian, I would hope that you are offended at any Christian comparing Jesus' blood atonement to ANY political struggle in any country.
