Speaking of Abraham, the Bible says, "By faith Abraham obeyed when he was called to go out to the place which he would receive as an inheritance. And he went out, not knowing where he was going. By faith Abraham, when he was tested, offered up Isaac, and he who had received the promises offered up his only begotten son, of whom it was said, 'In Isaac your seed shall be called, ' concluding that God was able to raise him up, even from the dead, from which he also received him in a figurative sense." In this book, you will learn about Abraham, who is the father of faith and from whom all the families of the earth are blessed.
