Quote from morganist:
"..If there is any kind of salvation or purification from the nature of humanity then are the sins we commit now the limitation as to whether we are entitled to receive it...."
Since you have answered my question regarding what authority the answer to your question regarding sin and salvation shall be based upon, I offer the following:
(As one who endeavors to follow Christ, I am somewhat concerned that the present day "church" has relegated one of its main functions to the back of the proverbial bus, the function of teaching and instruction in the Creedal statements of the historical church. In my opinion, one of the great confessions of the church is the
Heidelberg Catechism (1576 A.D.). This catechism was written by Zacharias Ursinus and Caspar Olevianus. It is a series of 129 questions and answers that teach the Biblical doctrines. I have tried to match the questions from the catechism that seemed relevant to your question as best I could)
3.Q. From where do you know your sins and misery?
A. From the law of God.
4.Q. What does God's law require of us?
A. Christ teaches us this in a summary in Matthew 22: You shall love the LORD your God with all your heart, and with all your soul, and with all your mind. This is the great and first commandment. And a second is like it, You shall love your neighbor as yourself. On these two commandments depend all the law and the prophets.
5.Q. Can you keep all this perfectly?
A. No, I am inclined by nature to hate God and my neighbor.
60.Q. How are you righteous before God ?
A. Only by true faith in Jesus Christ. Although my conscience accuses me that I have grievously sinned against all God's commandments, have never kept any of them, and am still inclined to all evil, yet God, without any merit of my own, out of mere grace, imputes to me the perfect satisfaction, righteousness, and holiness of Christ. He grants these to me as if I had never had nor committed any sin, and as if I myself had accomplished all the obedience which Christ has rendered for me, if I only accept this gift with a believing heart.
81.Q. Who are to come to the table of the Lord?
A. Those who are truly displeased with themselves because of their sins and yet trust that these are forgiven them and that their remaining weakness is covered by the suffering and death of Christ, and who also desire more and more to strengthen their faith and amend their life. But hypocrites and those who do not repent eat and drink judgment upon themselves.
88.Q. What is true repentance or conversion of man?
A. It is the dying of the old nature and the coming to life of the new.
114.Q. But can those converted to God keep these commandments perfectly?
A. No. In this life even the holiest have only a small beginning of this obedience. Nevertheless, with earnest purpose they do begin to live not only according to some but to all the commandments of God.
