How do we know God may withdraw His word from us?

In Revelation 2:5, God reminds the church at Ephesus to repent lest He remove their candlestick. This implies that when a church or people becomes complacent and fails to seek God earnestly, they risk experiencing a spiritual famine. A spiritual famine can occur when believers do not actively pursue God's word or fail to honor His commands, eventually leading to a withdrawal of His presence and counsel. God knows how to get our attention, and sometimes He allows periods of silence, not because He does not care, but so that we may recognize our desperate need for Him and His Word.
