Could not God rescue Israelites without blood on the doorposts?
Those sentences which are colored in orange are from Maharishi Dayananda Saraswati book Satyarth Prakash (The Light of Truth) and those which are colored in black are Jerry Thomas’s response.
"…..kill the Passover. And ye shall take a bunch of hyssop, and dip it into the blood that is in the bason, and strike the lintel and the two side-posts with the blood that is in the bason; and none of you shall go out at the door of his house until the morning. For the Lord will pass through to smite the Egyptians: and when He seeth the blood upon the lintel, and on the two-posts, the Lord will pass over the door, and will not suffer the destroyer to come in unto your houses to smite you." 12:21 – 23.)C. This looks more like making a charm. Can such a God ever be All-knowing who could not know the houses of the children of Israel but by seeing blood prints )on their lintels and side-posts). This is more like a man with a poor understanding. It shows that these things were written by some savage.
Answer: In fact, when one reads this passage properly and reads the rest of the Holy Bible, one can understand that the God of the Holy Bible is an omniscient God.
This Passover Lamb was the shadow of the sacrificial death of Jesus Christ for the sins of the humanity so that we are no longer under death but have won over it.
In other words, for thousands of years before the crucifixion of Jesus Christ, God was teaching humanity how He will save the people from bondage and death.
1 Corinthians 5: 7 “Therefore purge out the old leaven, that you may be a new lump, since you truly are unleavened. For indeed Christ, our Passover was sacrificed for us.”
