Yeshua/Jesus said, “I am the Way, the Truth, and the Life. No man comes to the Father but by Me.”
Then Yeshua/Jesus is the embodiment of the Way, the Truth, and the Life.
The Way is faith.
There is a mystical side beyond the rational that can only be accessed by a supernatural response from God to faith.
It is then “Christ in you the hope of glory.”
It is the living spirit of Christ in you that is the “hope of glory.”
And that living Presence is made possible by the Holy Spirit of God entering the body of the one who believes.
That Presence provides enlightenment and empowerment for living while bringing the believing one into the presence of the Father.
This is “the kingdom that is not of this world.”
In all wisdom and insight He made known to us the mystery of His will, according to His kind intention which He purposed in Him with a view to an administration suitable to the fulness of the times, that is, the summing up of all things in Christ, things in the heavens and things upon the earth.
