The Way,
The first doorway that led to the outer Court.
the place of sacrifice and the lavor where the priests washed and looked in the mirror to make sure they were not dirty before they offered the sacrifice.
The Truth,
This was the second doorway that led to the Inner Court, where the table of showbread and the giant menorah or lamp stand stood.
and then The Life,
The third doorway or entrance into the Holy Of Holies, which was blocked by the veil, where the Ark of the Covenant, representing the Presence of God stood.
In John 14:6,
Jesus answered, “I am The Way, and the Truth and the Life. No one comes to the Father except through me.
Yeshua was saying he was the doorway to the offering, sacrifice.
He was the doorway to the inner Court the bread of life and the light of the world.
And he was the doorway into the Holy of Holies.
And it was his blood that was put upon The Mercy/Life, seat for the forgiveness of sins.
This is why the religious Jews were so cut to the heart. When Jesus said he was The Way, The Truth, and The Life.
They knew that the Messiah/Announced One, would Tabernacle with man and be called Emmanuel,(meaning, God with Us.) Isaiah 9
They were looking for someone to free them from Rome not a spiritual King,
Who was the King of a spiritual Kingdom.
This is most likely the reason that the disciples, after Jesus resurrected and ascended,
called themselves the followers of The Way.
The Gentiles that believed in Yeshua, were called Christians. Eventually the name stuck as they were all Messiah/ anointed One, followers.
And I agree, loving the Lord your God with all your heart with all your mind and with all your strength and loving your neighbor as yourself is the only true way of love!
