Hebrews 10:26 To the thread name. Why in the world would you ask? That's a no brainer.
For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
Mistakes and non willful sin will occur. The heart condition toward God through Christ is what matters. If we are apathetic concerning this, we are doomed to eternal death.
This post shows great understanding of what God is looking for. He understands that will will make mistakes, that we will fall, He also wants us to be forgiven and get back up and strive to overcome sin.
Psa 130:3 If thou, LORD, shouldest mark iniquities, O Lord, who shall stand?
Psa 130:4 But there is forgiveness with thee, that thou mayest be feared.
Pro 24:16 For a just man falleth seven times, and riseth up again: but the wicked shall fall into mischief.
What does He look for?
Luk 17:3 Take heed to yourselves: If thy brother trespass against thee, rebuke him; and if he repent, forgive him.
Luk 17:4 And if he trespass against thee seven times in a day, and seven times in a day turn again to thee, saying, I repent; thou shalt forgive him.
If you are to forgive a brother, isn't that an example of what God does for us?
Act 3:19 Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord;
We are to repent, become converted (notice become is progressive? A continuing process Rom 7:14-25) and our sins are blotted out?
God nowhere says that He does away with the Law, what He does do is apply the sacrifice of Jesus Christ to our sins to PAY for them.
