The symbol for Day Five is a lamb and the story is told from Genesis 22 about Abraham taking Isaac to sacrifice him as an act of faith and obedience. God provided a ram as a subsitute so that Isaac did not have to die. This was a foretelling of what God would provide as a subsitute for us: His Son, Jesus.
I love the name for God that comes from this passage: Jehovah-Jirah, which means, "The Lord will provide." This has come to have such personal meaning for me as I have seen God's provision in my life. I am so thankful to God for providing the Lamb that took away my sins and for providing the Holy Spirit to dwell with me and guide me as I live my life.
"Behold the Lamb of God, which taketh away the sin of the world." John 1:29b
