What does the Bible say about slothfulness?

Scripture teaches that slothfulness is not merely a lack of effort but a spiritual attitude that reflects a deeper issue within the heart. In Proverbs 26:13-15, we see the slothful man making excuses for his inaction, using the absurdity of a lion in the streets to justify his laziness. This verses contrast the slothful state with action, showing that he may appear active, just as a door on its hinges moves but does not progress. These portrayals expose the heart's true disposition - a heart that is spiritually dead and seeks comfort in excuses rather than obedience to God's call.
