Trust Is A Derivative of Truth In The Bible. Truth Is Love.

John 18:37 (KJV) 

Pilate therefore said unto him, Art thou a king then? Jesus answered, Thou sayest that I am a king. To this end was I born, and for this cause came I into the world, that I should bear witness unto the truth. Every one that is of the truth heareth my voice.

Ephesians 4:15 (KJV) 

But speaking the truth in love, may grow up into him in all things, which is the head, even Christ: 

For God So Loved The World That He Gave His One And Only Son (From John 3:16) — 1 John 4:14 (KJV): And we have seen and do testify that the Father sent the Son to be the Saviour of the world.

John 14:6 (KJV) 

Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. 

John 1:14 (KJV) 

And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
