Blind - John 9

John 9:41 "Jesus said to them, if you were blind, you would have no sin; but since you say, we see, your sin remains."

Wherever there's lack, the lack itself will take us or motivate us to the throne of God and to ask for His blessing. Like Job, the lack that the enemy had caused him enabled his double blessings.
If we recognise our lack or weakness and come to His mercy seat, we'll be forgiven and be blessed.
Where there's no lack, where we can't recognise our sin and weakness, we simply won't be bothered to come to God for His mercy and blessing, so our lack remains in us, and everything stays the same.
