Now the boy Samuel was ministering to the Lord in the presence of Eli. And the word of the Lord was rare in those days; there was no frequent vision.
1 Samuel 3:1
I think one of the saddest accounts of scripture is the early story of Samuel. The young boy who was a gift from God became a rare gift back to God. He was devoted to service at the tabernacle in Shiloh where Eli the high priest and his corrupt sons led Israel's worship. Eli's sons had turned the priesthood into a shameful money and sex scam that disgusted the Lord. And even after Eli was told it displeased God, he did nothing about it. And the Word of God had grown scarce in these conditions. Yet faithful young Samuel would be used by God in these moments to restore God's Word to prominence and reform the tabernacle worship.
God will work even in a culture that rejects Him and opposes His truth. He will still speak to those who seek Him, even in times when respect for His Word is very scarce. He will show Himself strong even in the leanest of spiritual stirrings. One woman cried out to Him in desperation for a son. He answered her prayer with a mighty gift to the entire nation. Samuel became Israel's leader, prophet, and priest.
I am not worried that Christianity will disappear from Western culture as it becomes more secularized and anti-"God" in its orientation. Neo-paganism will not stamp out the truth. I plan on proclaiming it until I die. The Word may grow scarce, but it will be as strong as ever in the impact of those who believe it, ready to spring forth again. Even one believer will be used mightily by the Lord to bring truth to the world. Samuel's story is of just that sort of thing happening in a dramatic way.
