John 8:15-20 (NIV)
15You judge by human standards; I pass judgment on no one.
16But if I do judge, my decisions are right, because I am not alone. I stand with the Father, who sent me.
17In your own Law it is written that the testimony of two men is valid.
18I am one who testifies for myself; my other witness is the Father, who sent me.”
19Then they asked him, “Where is your father?”
20“You do not know me or my Father,” Jesus replied. “If you knew me, you would know my Father also.”
Hebrews 11:1 (ESV)
Now faith is the assurance of things hoped for, the conviction of things not seen.
Matthew 3:16-17 (ESV)
16 And when Jesus was baptized, immediately he went up from the water, and behold, the heavens were opened to him, and he saw the Spirit of God descending like a dove and coming to rest on him; 17 and behold, a voice from heaven said, “This is my beloved Son, with whom I am well pleased.”
