They were all sinners. Moses was punished for sin,did not enter promised land.
Moses didnt enter into the promised land because he already did when God opened up His kingdom in that man on the mountain. The kingdom of God. doesnt come with observation, it is within you, Luke 17:20-021. That promised land is not a physical place, it is a spiritual place for God and all of His heaven is Spirit and man is the temple of Him.
Mose was already in that promised land, the land God offered to all who will walk into His kingdom. Even Jesus had that option in Matt 3:16 when he entered into that land where God lives within.
He is at your door knocking this day and whoever opens it and lets Him in He will come to you and sup with you and be in you and you in Him as one. Jesus learned this lesson in Matt 3:16, Adam learned this lesson in Gen 3:22, Avraham learns the same lesson, Moses did on the mountain, Jesus did in a river, 120 did in an upper room and all today who let Him in and walk as He walks in His same light in His kingdom.
Jesus referred to this new land as born again a renewing of the mind to think in Spiritual terms that God is.
People today are like thew Hegrew out from Egypt, they sook a man to lead them to that ending, and they do the very same today looking for a messiah as a man to come and save them just as they did with Moses. Moses couldn't save them no more that Jesus could, all they could do is be that witness of that promised land. Moses and only two others out of a million entered into Gods rest. And even today very few who find His ways and enter into His. Luke 17:20-21.
As far as a sinner, Jesus was a sinner to the max by the laws of the Jews and paid the price for being against their laws as a blasphemer, liar, wine bibber, glutton, charged with hatred, scandals and lies. He became sin by those who saw him as a sinner. It is the very same today when someone who has from God that what Jesus had from God Himself and made perfect even as my Father in heaven is perfect are charged with blaspheme accusing God and Jesus as gnostic liars. Some here charge the ways of God and Jesus to be like them as gnostic liars. Crucifying the christ with their own doctrines for sin.
To these to be perfect and have the same mind as Jesus had from God and walk as He walks in it with the same signs following -- they charge as sin, blaspheme, only because they cant be that person of Christ that God demands of us if we are to be of Him.
Moses led to to Gods salvation, ironic is Jesus didnt lead any of his disciples to salvation for ever single one of Jesus disciples flat out rejected to be identified with him in his trials and tribulation, not one came to him to be identified with him. It pretty much is the same today.
How many do you know that is perfect even as your Father in heaven is perfect and walk as He walks in His same light as Jesus did with the same signs following? You know at least one and you are talking to him in this very letter, but I would bet that you won't believe him either just as those of the day didnt believe Jesus, and we have the very same father who is God, Jesus was my brother, we have the same Father who is God.
That is why Jesus so stressed the point of ye must be born again with a renewing of the mind to think in Gods terms just as He did. God calls to have His mind, or Spirit the mind is called, Born Again, ye must be born again or you will be like the million who never made it.
