A number of years before David became King over Israel the nation had been at war with their enemy the Philistines. The Ark of the Covenant had been brought to the battle field in the hope it would inspire Israel and empower them to defeat their enemy. They not only lost the battle, but they lost the Ark of the Covenant to the Philistines.
Eli the high priest fell over and died when he heard the news and his daughter-in-law gave birth to a baby boy and called him Icabod meaning the “Glory had Departed!” So it was a serious matter to lose the Ark of the Covenant because it meant the departure of God’s presence. The Ark was returned to Israel and it stayed in the house of Abinadab for many years and his house was blessed mightily because God’s Presence (The Ark) was in his home.
When David became king he wanted the entire nation to be blessed and be restored to the presence of God so he sought to have the Ark returned to Jerusalem. David discovered through tragedy that the Ark had to be carried properly on the shoulders of anointed priests. As New Testament believers we are told our bodies are the temple of God (or like the ark – the place where God’s presence dwells) and we need to be careful and respectful in the way we carry God’s presence! If done properly He will show up and bless everything we touch. Sound okay?
