Truth is one and eternal. Realize oneness with it in your deathless Self, within.
The following commentary is based on the teachings of Paramhansa Yogananda.
In the Gospel of St. John, Chapter 1, we read:
The law was given by Moses, but grace and truth came by Jesus Christ.
Grace means the power to rise, spiritually. Truth means the experience of divine realities, not the application in the outer world of that inner experience.
Divine love is the soul’s experience of oneness with God. Kindness is the human manifestation of that love. Grace is deeper than mere kindness.
Wisdom is a divine experience. Justice to all is a human law, though divinely inspired. It follows as a consequence of the experience of wisdom. Truth goes deeper than mere justice.
While following the law, we should strive always to trace it back to its origins in the vision of God. Therefore Krishna in the Bhagavad Gita urges the devotee not to be satisfied with spiritual precepts alone, but to go beyond them to the direct, inner experience of truth. In the eighteenth Chapter of that great Scripture he says:
Nay! but once more
Take My last word, My utmost meaning have!
Precious thou art to Me; right well beloved!
Listen! I tell thee for thy comfort this.
Give Me thy heart! adore Me! serve Me! cling
In faith and love and reverence to Me!
So shalt thou come to Me! I promise true,
For thou art sweet to Me!
And let go those –
Rites and writ duties! Fly to me alone!
Make Me thy single refuge! I will free
Thy soul from all its sins! Be of good cheer!
Thus, through holy Scripture, God has spoken to mankind.
