No born again person is without sin . If we say we have no sin, we are not being truthful. Why? Because we have that spiritual side which is willing to not sin but we have the "human nature" side which is sometimes difficult to control. As long as we are in these bodies of flesh, we will sin; omission, commission.
Praise God we have someone who has covered our sins with His blood
In the grace wherein we not stand Romans 5.....and because of this positioning of grace.....where sin abounds, grace abounds the more. <--written unto the saved!
