What is really sin for those of us who are New Covenant Christians. The best answer I have found is found in 1Jn3.
Not one word about keeping the old covenant Sabbath in the following. If we cannot receive the Holy Spirit unless we keep the Sabbath why isn't mentioned in the following truth filled words?
3 See what great love the Father has lavished on us, that we should be called children of God! And that is what we are! The reason the world does not know us is that it did not know him. 2 Dear friends, now we are children of God, and what we will be has not yet been made known. But we know that when Christ appears, we shall be like him, for we shall see him as he is. 3 All who have this hope in him purify themselves, just as he is pure.
4 Everyone who sins breaks the law; in fact, sin is lawlessness. 5 But you know that he appeared so that he might take away our sins. And in him is no sin. 6 No one who lives in him keeps on sinning. No one who continues to sin has either seen him or known him.
7 Dear children, do not let anyone lead you astray. The one who does what is right is righteous, just as he is righteous. 8 The one who does what is sinful is of the devil, because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the devil’s work. 9 No one who is born of God will continue to sin, because God’s seed remains in them; they cannot go on sinning, because they have been born of God. 10 This is how we know who the children of God are and who the children of the devil are: Anyone who does not do what is right is not God’s child, nor is anyone who does not love their brother and sister.
More on Love and Hatred
11 For this is the message you heard from the beginning: We should love one another. 12 Do not be like Cain, who belonged to the evil one and murdered his brother. And why did he murder him? Because his own actions were evil and his brother’s were righteous. 13 Do not be surprised, my brothers and sisters, if the world hates you. 14 We know that we have passed from death to life, because we love each other. Anyone who does not love remains in death. 15 Anyone who hates a brother or sister is a murderer, and you know that no murderer has eternal life residing in him.
16 This is how we know what love is: Jesus Christ laid down his life for us. And we ought to lay down our lives for our brothers and sisters. 17 If anyone has material possessions and sees a brother or sister in need but has no pity on them, how can the love of God be in that person? 18 Dear children, let us not love with words or speech but with actions and in truth.
19 This is how we know that we belong to the truth and how we set our hearts at rest in his presence: 20 If our hearts condemn us, we know that God is greater than our hearts, and he knows everything. 21 Dear friends, if our hearts do not condemn us, we have confidence before God 22 and receive from him anything we ask, because we keep his commands and do what pleases him. 23 And this is his command: to believe in the name of his Son, Jesus Christ, and to love one another as he commanded us. 24 The one who keeps God’s commands lives in him, and he in them. And this is how we know that he lives in us: We know it by the Spirit he gave us.
We have been told that we do not have the Holy Spirit in us because we do not keep all of the ten commandments. We are, as on poster put, it of Babylon according to one poster. I have a terrible time swallowing his theory and the above scripture tells me I belong to the truth not by keeping ritual old covenant laws, nor eating certain foods and not by keeping some man made tithing system. It tells me that if I believe in Jesus, believe He died for me and made me white as new snow and if I love all of His children as He commanded in Jn 15:10-14 I belong to the truth as written in verse 19.
All of the long drawn out posts in this thread are for naught. They are meaningless in the light of the new and better covenant Jesus gave all mankind which has superseded the covenant given only to one nation, Israel. Eph 2:15 by setting aside in his flesh the law with its commands and regulations. His purpose was to create in himself one new humanity out of the two, thus making peace, 16 and in one body to reconcile both of them to God through the cross, by which he put to death their hostility. 17 He came and preached peace to you who were far away and peace to those who were near. 18 For through him we both have access to the Father by one Spirit.
Anyone that tries to tell us we have to obey old covenant ritual laws like Sabbath observance has yet to see the truths found in the New Testament.
