Judges 5:2 Praise ye the LORD for the avenging of Israel, when the people willingly offered themselves.
This is a part of a song by Deborah and Barak. God had just delivered them from the hand of their enemies. In this verse, they praise the Lord for avenging them of their enemies. They had been oppressed by Jabin, King of Canaan, for 20 years before God delivered them. God waited until they cried out to Him and offered themselves willingly before He delivered them from their enemies.
God is looking for us to offer themselves to Him willingly.
How would God use us if we would offer ourselves willingly to the Lord?
