Well, I suppose that leaves us both staggered because it plainly says all throughout the Bible that this other covenant was NOT from God, it was the works of MAN.
1 Corinthians 10:3 tells us “Moreover brethren I do not want you to be unaware that all our fathers were under the cloud, all passed through the sea, all were baptized into Moses in the cloud and in the sea. All ate the SAME SPIRITUAL FOOD( the bread of heaven) and all drank the SAME SPIRITUAL DRINK. For they drank of the spiritual Rock that followed them and that Rock was Christ.”
This means that those coming out of Egypt received the SAME spiritual teachings as that which Jesus taught, the SAME word. They were given the WAY OF LIFE. However, some turned away and followed their own way as it says, Romans 1:25 “They exchanged the truth of God for a lie and worshipped and served CREATED things rather than the Creator.”
Psalm 106:20 “They made a calf in Horeb and worshipped a molten image. Thus they exchanged THEIR GLORY for the image of an ox that eats grass. They forgot God their Savoir.”
Deut. 32: 18" Of the Rock who begot you, you are unmindful and have forgotten the God that fathered you."
The list of verses go on and on. I don’t see how you can miss it.
Isaiah 1:10-17 “To what purpose is the multitude of your sacrifices to Me? I have had enough of burnt offerings of rams, and the fat of fed cattle. I do not delight in the blood of bulls or lambs or goats.Vs. 13 incense is an abomination to Me, the new moons, the Sabbaths, and the calling of assemblies. Your new moons and appointed feasts Mt soul hates…Cease to do evil and learn to do good, reprove the oppressor, defend the fatherless, plead for the widow…”
ALL the books of the prophets say the SAME thing. The books of the New Testament say this as well. They were following man made doctrines(Mark7:7, Matt.15:9,Col 2:22, Titus 4:4 Romans 1:21-23 etc. etc. etc.
