Romans 4:1

"Look unto Abraham your father, and unto Sarah that bare you: for I called him alone, and blessed him, and increased him."

"Therefore it is of faith, that it might be by grace; to the end the promise might be sure to all the seed; not to that only which is of the law, but to that also which is of the faith of Abraham; who is the father of us all,"

"Your father Abraham rejoiced to see my day: and he saw it, and was glad."

"Are they Hebrews? so am I. Are they Israelites? so am I. Are they the seed of Abraham? so am I."

"Men and brethren, children of the stock of Abraham, and whosoever among you feareth God, to you is the word of this salvation sent."

"What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet."

"And think not to say within yourselves, We have Abraham to our father: for I say unto you, that God is able of these stones to raise up children unto Abraham."

"Bring forth therefore fruits worthy of repentance, and begin not to say within yourselves, We have Abraham to our father: for I say unto you, That God is able of these stones to raise up children unto Abraham."

"They answered him, We be Abraham's seed, and were never in bondage to any man: how sayest thou, Ye shall be made free?"

"Art thou greater than our father Abraham, which is dead? and the prophets are dead: whom makest thou thyself?"
