As we will see in the Bible, God often used visual aids as object lessons to teach people specific truths He wanted them to understand. God used these visual aids in much the same manner that we would use the blocks to teach children truths. We perceive things through our physical senses much more clearly than we do through our spiritual senses.
In view of this, when God began to teach His covenant people, the Israelites, He did so through the use of visual aids which the Israelites could comprehend with their physical senses. God gave these visual aids in the Hebrew Scriptures (Old Testament part of the Bible) in the form of the various religious laws and rituals which the Israelites were to observe. As the Israelites practiced these laws and rituals, they would learn through their physical senses, spiritual truths concerning their relationship with God.
The time came when the Israelites were to put away these physical symbols and enter into the spiritual reality which they portrayed. The transition from the physical to the spiritual was provided for them through the person and work of Jesus Christ, the Jewish Messiah and Savior of the world.
