Does the Father cast us away?

Does the Father cast us away? There's a world of a difference between sinning as a believer and getting cleansed in the blood of Jesus vs trampling the Son of God underfoot and crucifying the Son of God again. Who can say we have not sinned after turning to Christ? Which one of us can say we haven't sinned willfully after turning to Christ? If you've been a believer long enough you will realize you have sinned and also sinned willfully and God has forgiven you. We're seeking to be overcomers and not sin but to walk in Love and Power, but if we do sin we have an advocate with the Father Jesus Christ the Righteous and we receive forgiveness and the blood of Jesus cleanses us from all sin.
