His yoke is easy. The old commandments were impossible to keep. No one ever did it.
No one therefore was supposed to! They were supposed to try and see how they failed. Then they would know they needed Him.
The evil deed that leads to death is rejecting and not believing Jesus. That of course is followed by many other wicked deeds. The ones resurrected to eternal life did the deed of believing in Jesus. Then, of course (moreso in some than others) they also had some good deeds as a result. Those deeds are not what saved them.
If by the Old Commandments you mean the Laws of Moses, then I agree.
Not all the 613 Laws were from God...some were instituted by Moses.
BUT,,,the Israelites WERE SUPPOSED to keep the Law.
God made a Covenant with Moses....
To make it simple, the people were to honor and obey God,,,
They would be His people,
and He would be their God.
But they couldn't obey, as you've stated...but not because they weren't supposed to.
The Law showed them they could not keep it....
But where there is no law, the people are a law unto themselves.
Read chapter 2 of Romans.
And as to John 5:28
The verse if VERY CLEAR.
I find it amazing at how we change what simple verses say to satisfy our own belief system.
This is called eisegesis and is no way to read the bible.
Jesus said that those doing good deeds will be rewarded
and those doing evil deeds will be damned.
Simple.
