Nor was there any deceit in His mouth.
Isaiah 53:9 NASB
The two statements “God is Love,” and “I am the truth” show us that truth is just as much a part of the divine nature as is love.
Jesus is truth. He’s not just an honest man. He’s not just an honest opinion. He’s not just a valid way of looking at things.
He is THE Truth. He – Jesus – the Word of God in human form – is the Truth.
Not only was everything that He said true, but all truth has its root – its foundation – in Him.
Just as all love comes from the source of all love – Our Father.
We love, because He first loved us. - 1 John 4:19 NASB
By the same reason everything that is true has at its core Jesus.
By contrast satan is called the father of lies. Any twisting of truth is at its root demonic – satanically inspired.
