Ecclesiastes 7:20
For there is not a just man on earth who does good and does not sin.
Romans 5:7-9
For one will scacely die for a righteous person -though perhaps for a good person one would dare even to die- but God shows his love for us in that while we were still sinners, Christ died for us. Since, therefore, we have now been justified by His blood, much more shall we be saved by Him from the wrath of God.
1 John 4:19
We love Him, because He first loved us.
