Certainly this level of sacrifice would please the god of fertility. A sacrifice is giving up of one thing for a greater thing. A sacrifice can be a good thing. In a sacrifice bunt we give up the privilege of reaching base in order to advance a runner to second or third. We sacrifice a present fulfillment in order to reach a more important future goal.
Parents sacrifice many personal dreams in order to provide for their children.
We are in fact to present our very lives, body and soul to God as a living sacrifice. We are to lay down our lives for Him. Jesus Christ lay down hid very life as an atoning sacrifice for our sins, sacrificing his life, even that most intimate of bonds with God the Father, as an atoning sacrifice, fulfilling the curse of the law. It's not that sacrifices are wrong in themselves. It depends on what is being sacrificed and to and for what the sacrifice is being made.
