One can speak for all when scripture says that all have sinned and fall short, and that if anyone says they are without sin, they are a liar.
I knew right from wrong, and had a conscience that found it hard to sin, before I was saved.
The same could be said of many atheists, that they could also know right from wrong and have a conscience that doesn't want to sin.
Since we have scripture that tells us that all have sinned and that any that say they are without are liars, then we can conclude that the Holy Spirit hasn't made anyone stop sinning.
Not sure why you would say "every day" or "know in your heart".
Sin is sin whether you sin once or every day, or whether you knew it in your heart or not.
So it has never been a question of how much or little you sin.
I don't know of a single instance when GOD chastened or scourged me when I sinned.
That sort of mentality is akin to what Job's friends kept saying to him ----- "Geeze, Job, these awful things wouldn't be happening to you unless you did something wrong to be chastised for".
They were the ones doing wrong, and yet it was Job that was suffering, not them.
When I was about eight or nine-years old, I wasn't a Christian, my family didn't go to church except once on Christmas and once on Easter, I knew NOTHING about God, yet, when some friends wanted me to go with them and steal candy from a store, I knew it was wrong somehow and refused to participate. As a child I had a very strong conscience. My Mom would tell me to sit in a certain chair while she went to the store and when she got back I was sitting in that exact chair in total obedience. (My Sister was a different story.) Another time when I was eight or nine my Mom took us kids to a Department store and I opened a Halloween costume box and accidently broke the string on the mask, so I went to my Mom, asked her for a nickel and went and placed that nickel in the costume box, in order to make amends for the damage I had caused.
I wasn't a Christian then, I didn't know who the Holy Spirit was nor did I really have a concept of God. All I had was a conscience to know the difference between right and wrong. Like you say, Tam, one doesn't need to be a Christian in order to make good choices in life, be obedient, be kind, be lawful, recognize consequences, etc. Like you said, an Atheist can do good things, provide good works/deeds, help the poor, respect their Parents, obey the laws of the land, not steal, lie, cheat, etc. The problem is, being a good person will not help you inherit eternal life, receive forgiveness of sins, or become a member of the Body of Christ.
There's a lot of really good people out there that aren't saved and will not spend eternity in Heaven, but, will end up in the Lake of Fire and eternal damnation. Being a good person doesn't cut it with God. The Bible says in
Isaiah 64:6;
"But we are all as an unclean thing, and all our righteousnesses are as filthy rags; and we all do fade as a leaf; and our iniquities, like the wind, have taken us away."
God sees the
righteousness of human beings as
'filthy rags.' So, if one should find themselves standing before Almighty God at the judgement for the unbelievers, they can rest assured, that God will NOT be impressed with their
'righteousness, good works/deeds.' In fact, the Bible says in
Revelation 20:12 "And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works." So, we already KNOW what God thinks about, good works/deeds/righteousness. He thinks they're like 'filthy rags.' How far will the unbelievers get with their 'righteousness' before a totally righteous and perfect God, who MUST punish sin of any kind?
The Bible says in James 2:10; "For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all."
According to that verse of Scripture, if someone/anyone would be able to obey the ENTIRE law, yet, they disobeyed even ONE of the laws, they would be GUILTY of disobeying EVERY law. If a person believes they're capable of being 'good enough' to enter into the presence of God, they'd be mistaken, because, in order to spend eternity in Heaven with God, you'd have to have NEVER sinned throughout your ENTIRE life. Basically, you'd have to be the Lord Jesus Christ. He was 100% sinless throughout His entire life, He's the ONLY one that ever accomplished that. So, if someone thinks they can
'earn their way to Heaven' through 100% obedience to the law, they'll have an extremely rude awakening. Actually, you have to be equivalent to Christ in order to be in the presents of God for eternity.
That's why, when we hear the Gospel and place ALL of our faith in Christ as our Lord and Savior, we actually become a 'Child of God' who, in the eyes of God is sinless. We are sinless, because, Christ took our place and paid the price for all of our combined sins; past, present and future. Therefore, God can look on us and ONLY see His Son. (God the Son) If not for Christ's death and resurrection, the human race would ALL stand before a righteous God and be condemned to the 'Lake of Fire' for eternity. God doesn't take sin lightly, it cost Him the blood of Jesus, His Son. (God the Son) And, He was willing to pay that price, out of His love for us.
