If I knew without a shadow of a doubt that God wanted me to kill my child for any reason, I most certainly would. I love God with all my being. He rescued me from everything in life. Yes, God is all-knowing, but He wanted to test Abraham's faith through it. He knew beforehand that Abraham was willing, but Abraham did not know before. God puts trials in the lives of every single human being to draw them closer to Him. It may not seem like it most times, but I guarantee it has a purpose. God did really love Abraham too. He loves every single living thing on this planet because HE made it, and molded it after His own image.
