The ark of the testimony was a wooden box, covered in gold inside and out. It had four exterior rings through which poles could be attached for carrying. No one but the high priest could touch the ark (Numbers 4:15). To do so would result in instant death, as happened with a man named Uzzah (2 Samuel 6:1–7). God was beginning to teach His people about His holiness and their unworthiness. He demonstrated to them that His commands were not suggestions to be negotiated. He wanted to teach them to obey Him in all things, whether or not they understood the reason for the rules.
The lid of the ark was also made of gold and formed a seat between two cherubim, called the mercy seat. It was there that God would meet with His people (Exodus 25:22). Inside the ark of the testimony, Moses placed the tablets of the Law that God gave him on the mountain. The ark was placed inside the tabernacle in the most holy place, where only the high priest could go once a year (Exodus 26:34). Through it all, God was painting a picture to help us understand what is required for sinful man to come into the presence of a holy God.
The ark of the testimony got its name from the fact that it would be the housing for God’s testimony to His people. His Law was not only verbal, but written, etched in stone (Exodus 34:28; Deuteronomy 5:22), so there could be no excuse for disobedience. Hebrews 9:4 tells us that, later, the Israelites added to the stone tablets within the ark of the testimony a jar of manna (Exodus 16:32–33) and Aaron’s rod that budded (Numbers 17:8–10).
The ark of the testimony represented the presence of God with His people, and His power went with them wherever they took the ark (Joshua 3:6; Numbers 10:33–35). The enemies of Israel, the Philistines, stole the ark once (1 Samuel 5:1), hoping its power would help them. They set it in their idol’s temple and waited for the good luck it would bring. But calamity broke out among the Philistines, until they begged their leaders to send the ark back to Israel (1 Samuel 5:4, 6, 9, 11–12). God demonstrated that He was not a good-luck charm whose power could be had by whoever captured His ark. The power was not in the ark of the testimony itself; the ark only represented the presence of God with His people.
Since the death and resurrection of Jesus (Romans 14:9), God no longer uses an ark of the testimony to dwell with His people. We are under a new testament or covenant. At Pentecost, He sent the Holy Spirit to indwell every believer (Acts 2:1–4, 38–39). We become His temple (1 Corinthians 6:19). When we have been born again by faith in Jesus Christ (John 3:3, 16), we take God with us everywhere we go. It did the Philistines no good to harbor the ark, because the ark had no power in itself if God was not on their side. Likewise, we do not need physical items—crosses, images, holy relics—to carry the power of God with us because He already abides in us. That awareness of His presence, called the fear of the Lord (Psalm 19:19; Proverbs 15:33), helps us make decisions that honor Him.
