Do you really believe that, in this life, you CAN be sinless?
WE all like sheep have gone astray.
He who says he is without sin is a liar.
We will all die as sinners. ALL.
Some of us sinners will have accepted Jesus Christ as their Savior and will be covered by His perfect, PERFECT, sacrifice. He is sufficient. Those will go to heaven, stand before God, who will see the righteousness of His Son.
Some will die unsaved, unrepentant. They will stand before God in the rags of their OWN righteousness. And be dismissed for it.
For me, Jesus is all I need for heaven. Nothing man can do will add to that.
If I just walked out of the Confessional and was killed, yes, I would be sinless.
