Abraham was the first person to fully trust in one God. God told Abraham to leave his home and travel to a new country, promising that Abraham and his wife Sarah would have a child, though they were unable to conceive. Abraham obeyed God and traveled to Canaan with his family. Later, God tested Abraham by commanding him to sacrifice his son Isaac, proving Abraham's complete trust in God. Abraham is significant to Judaism, Christianity, and Islam for being willing to fully submit to God.
