God stated in the 2nd commandment of the 10 commandments that His people were not to make any images to worship (Ex 20:4). The fact is, God had already created an image of Himself in Genesis 1:26-27 when He made mankind in His image and likeness. When we love others, we give God a true sacrifice (Heb 10:5-7, Psalms 50:14 & 23, Psalms 51:16-19), greater than any animal sacrifice offered by the Israelites in the Temple.
