Jesus already saved you from hell by His Atonement (Rom. 4:7), and by His Word, which says that even the unforgivable is forgivable (James 2:13). Not that He made you perfect, since we will always have our "sin nature" (1 John 1:8), but now, both all your sins, and your "sin nature" (pride, anger, lustfulness, etc.), are covered with His Blood and atoned for (Heb. 9:12; 1 John 2:2), since the Blood of Jesus atones for everything it touches. Yes, Jesus took up "sin" of even unbelievers (1 John 2:2), but, we still need to believe these things, and to thank God that we're saved (Luke 17:17-19), to make our faith in this truth alive (James 2:13). Even just a thanks is sufficient, because thanks is also an action. And immediately your living faith will save you!
