By faith Abraham obeyed when he was called… Hebrews 11:8

Look to Abraham your father, and to Sarah who bore you; For I called him alone, and blessed him and increased him. Isaiah 51:2

What does it profit, my brethren, if someone says he has faith but does not have works? Can faith save him? 15 If a brother or sister is naked and destitute of daily food, 16 and one of you says to them, “Depart in peace, be warmed and filled,” but you do not give them the things which are needed for the body, what does it profit?… Was not Abraham our father justified by works when he offered Isaac his son on the altar? James 2:14-16;21
