Shared ground
Ecclesiastes 5:1–3 assumes that worship is a real encounter “before God,” not merely a social event. The passage treats God as exalted (“in heaven”) and humans as limited (“on earth”), and it connects that gap to fitting posture in worship: careful approach, receptive listening, and restrained speech.
The text also links careless religion with moral blindness. “Fools” can participate in worship activity while “not knowing” they are doing wrong. In other words, external religious actions do not guarantee wisdom or moral clarity.
Where interpretation differs (only where needed)
Some readers take “draw near to listen” to mean primarily listening to instruction in the worship gathering (teaching, reading, wisdom). Others take it more broadly as an attitude of attentiveness to God in worship, including prayer.
Some read “before God” as mainly speech at the sanctuary (public prayers, statements, and especially vows, which the next verses address). Others extend it to all prayer and religious talk, even outside the sanctuary.
Why the disagreement exists
The disagreement comes from how specific the setting is meant to be. “God’s house” suggests a sanctuary setting, and the next section (vv. 4–7) speaks explicitly about vows. That pushes many interpreters to read these verses as warning against rash sanctuary speech. At the same time, the reasons given (“God is in heaven… you on earth,” “let your words be few”) are stated in general terms that can sound like a broader worship principle.
What this passage clearly contributes
Explicit in the text: approaching “God’s house” calls for guarded conduct; listening is better than the “sacrifice of fools”; fools can do wrong without recognizing it; people should not be rash or hasty in speech “before God”; and the God–human distance supports “few words.”
Reasonable theological inference: worship is not something humans manage through volume, speed, or religious performance. The passage treats restraint and attentiveness as marks of wisdom, and wordiness as a common symptom of inner disorder (like anxious cares producing restless dreams).
