John 8:54-58

Jesus answered, “If I glorify Myself, My glory is nothing; it is My Father who glorifies Me, of whom you say, ‘He is our God’;

and you have not come to know Him, but I know Him. And if I say that I do not know Him, I will be a liar like you; but I do know Him, and I follow His word.

Your father Abraham was overjoyed that he would see My day, and he saw it and rejoiced.”

So the Jews said to Him, “You are not yet fifty years old, and You have seen Abraham?”

Jesus said to them, “Truly, truly I say to you, before Abraham was born, I am.”
