In Numbers 15 we find that under the Law, a person would be forgiven of unintentional sin by means of a sin offering. Naturally, this could not be done until he was aware of his sin. The willful sinner who broke the Sabbath was not forgiven but stoned. It would seem there is a similar principle applied in the New Covenant. Are not the Christian's sins of ignorance covered by our sacrifice, Jesus, even while the person is unaware of them? And Hebrews 10:26, "If we keep on willfully sinning after we have received the knowledge of the truth, no sacrifice for sins is left". The different treatment of sins seems to be maintained in the New Covenant. God does not change.
It appears that now, under the new covenant, there is a dramatic change in God's dealing with sins:
Acts 17:30 The times of ignorance God overlooked, but now he commands all people everywhere to repent...
Romans 3:24-27 ... they are made righteous by his grace as a gift, through the redemption which is in Christ Jesus, whom God put forward as a means of mercy by his blood, to be received by faith. This was to show God’s righteousness, because in his divine forbearance he had passed over former sins [under the first covenant] it was to prove at the present time that he himself is righteous and that he makes righteous him who has faith in Jesus. Then what becomes of our boasting?
It is excluded.
I once believed "the born again" could go for a day or days without sinning, but I no longer believe this is true.
And I once believed that a regenerated persons could not go for one minute without sinning. Now I believe that they can. If it is possible for them to go for a single minute without sin, then why not two minutes?
How about three minutes? Five minutes? An hour? If they can go for an hour, why not five hours? Why not a day? A week? A month?
Jesus did not die to forgive us for past sins, but to deliver us from our present live sins. If none of us are delivered, then He died in vain!
I Corinthians 6:9-11 Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived; neither the immoral, nor idolaters, nor adulterers, nor sexual perverts, nor thieves, nor the greedy, nor drunkards, nor revilers, nor robbers will inherit the kingdom of God. And such were some of you [not "such are some of you"]. But you were washed, you were sanctified, you were made righteous in the name of the Lord Jesus Christ and in the Spirit of our God.
Sin is "missing the mark", the mark God sets for us, not the one we set.
Yes, the primary meaning of the Greek word "hamartia" is "missing the mark". Yet the New Testaments is full of texts containing "hamartia" where deliberate sin is meant.
Who among us can say they know exactly what God's will is for us at every particular moment? Remember, sins of ignorance are still sins.
None of us is yet perfected (completed) as children of God. So our deliverance from sin is not yet complete. Yet, "He who began a good work in your will bring it to completion in the day of Jesus Christ". So as long as the process of deliverance from sin continues in our lives; as long as we co-operate with the enabling grace of God, made possible through the death and resurrection of Jesus, then God will regard us as righteous persons now. But if we believe that it is impossible to live our lives without sin, then we have given up. In such a case, we may not be on the road to perfection. We ought to be concerned. For Jesus said:
"Not every one who says to me, ‘Lord, Lord,’ shall enter the kingdom of heaven, but he who does the will of my Father who is in heaven. Matthew 7:21
