The chaff blows away in the wind when winnowing the wheat. It is a separation of the usable nutrient from the non-useable chaff.
This is how God sees our true spirit, heart of faithfulness, and purposeful living, every day. It has nothing to do with your participation in church service, activities, business, and knowing scripture. It has to do with your daily heart posture and relationship with Jesus. How is your heart posture and Jesus time?
His winnowing fork is in his hand, and he will clear his threshing floor, gathering his wheat into the barn and burning up the chaff with unquenchable fire. Matthew 3:12
When God can use you in daily life for His purpose, you carry His Holy light. Can God use you to glorify His name and not your own, no matter if it offends others?
