Have you heard the good news? Your sins are not keeping you from the deep spiritual life, or even preventing you from the Kingdom of God! I don't care about how many or what type of sin. Sins or the lack thereof just isn't what matters.
Leviticus 17:11
For the life of a creature is in the blood, ...
Often we associate blood with death, and that carries over to how we interpret the word "blood" in the Bible. However, blood is not about death at all.
The New Testament has over 90 uses of blood, and only a couple of those are in association with sins. The overwhelming revelation is that it is the LIFE of God, through the blood of Christ that can save you! ... and that His death was necessary to prepare the world for salvation by His life!
We must not make the mistake of seeing the blood of Christ as a reference to His death. His blood is His life. His life is what we need, if the dead require if they want to experience freedom, and a fulfilling intimacy with God ... and ultimately to give us hope from perishing on the last day.
John 6
53 Jesus said to them, "I tell you the truth, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. 54 Whoever eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day. 55 For my flesh is real food and my blood is real drink.
If you are unwilling to partake of His life, then it won't matter how little you sinned or how many/few sins of yours are forgiven. The only way to be saved is through His life.
The only way to perish, is to be unwilling to be infused with His eternal life.
Do not anguish over your past sins for I have washed them away, all of them, past sin, present sin, and yes, your sins of tomorrow. ~ Jesus [Letters from God and His Christ - Volume 1 - Jesus Christs Love and Forgiveness Are With You]
