A baby Christian will do an act of lack of self-control and our conscience doesn't hurt. But the same thing 10 years later cannot be done because our conscience is now aware through growth of the fruit of the Spirit and the warning prevents us.
Looking back at my life as a baby Christian, I remember sinning with no guilt but God was still speaking to me regularly as if I was still sinless. How could that be? I only thought about this recently, and wondered how I could sin with no checking of my conscience, and still feel no separation from God. None of the multitude of gifts He gave me stopped working. (He's given me all but two. But they are for separate offices, and are no use to me for the office of teaching.) When I asked Him about our lack of separation, He said "because it was unintentional." Now I understood perfectly. That new revelation to me was scriptural. "New revelation" is the Author's interpretation, and undoes false teaching and the doctrines of demons. It has nothing to do with foretelling, but is actually forth-telling. However, today prophets can also receive personal foretelling as Agabus did to Paul, but not new scripture for the profit of all like John did with the Book of Revelation.
The first time around when our heart does not condemn us, God wipes it clean as "unintentional"
*with one condition. That is how God still sees babies as sinless. But 10 years later when it would be in full knowledge, God would hold us accountable if we kept disobeying our conscience when He's given us His Spirit to empower us to resist the devil, and eventually hearts could become seared as we quench the Spirit. This is why 1 John 5:18 tells us that those more mature keep themselves and do not willfully sin, and the devil cannot touch us. And the same text means that a baby Christian will live up to the knowledge they have; that living up to is keeping themselves and we can remain in a sinless state. Those unintentional sins we commit are trespasses, as per Leviticus 5:15, and
*Matthew 6:14-15 tells us that as long as we forgive those brethren who trespass against us, our trespasses are then cleansed. The power of Jesus has made our New Covenant through the Spirit just about fool-proof. It is so easy to be saved in Jesus, there is no excuse for false teachers to claim we will always sin. Besides walking in the Spirit, all we actually need to do is always forgive. That is brotherly kindness, and is a fruit that needs to mature to become perfect and holy as our Lord Jesus commanded.
Another thing I learned this year as I prayed on the way home from church was about our conscience. It is our heart where God promised to write all His laws. But are
all His laws written there and known day one when we are first born again, as I had first thought? God clarified that our heart/soul is born again of the Spirit, but on day one only the seeds of the fruit of the Spirit are planted, and still have to grow to maturity. Immature fruit causes those sins, but God prunes those branches to mature them and to produce bigger, healthier fruit, as long as we stay in the vine and abide in Jesus, there is no sin in Him. 1 John 3:6. And as for baby Christians who are children of God and abide in Jesus
continually sins, but are pruned by the Master Gardener.
Our spirit is also born again and full of righteousness. We cannot rebel against God. Now I realize my sin when a baby Christian was an immature fruit of the Spirit. But it was not in rebellion against God. In other words, it was not a sin of lawlessness which were already crucified from day one.
What this does not mean is that a born again Christian, even a baby one, has two natures. That is a false doctrine of demons taught by the most popular of teachers, some with popular books for itching ears, and even on the radio and youtube and other areas of the internet. Just ask yourself if you are one of their disciples, does their messages justify your known sinful ways, or cause you to become actually holy, and not because of the doctrine that the blood of Jesus covers up your sin. They also are against sinless perfection, even though we are sinless from day one due to intention, and are on the path to perfection in this life, not after we die. Wow, Satan wants all Christians to wait until after they die, because he cares not that you believe in Jesus (even he knows that much), just as long as you don't abide in Him, and He in you so you won't keep willfully sinning. That is the biggest clue of their forked tongues of a serpent.
Once you have the Spirit of Christ indwelling you to live up to the knowledge you have, you are NOT IN THE FLESH,
Romans 8:9, but in the New Covenant. Our intention is to always follow Jesus. Unfortunately, there are some Sunday Christians that go to church out of habit, cultivating friendships. The Spirit is still on the outside drawing them to Jesus, but until we actually repent and want to turn away from sin, Jesus can’t help us yet by dwelling inside killing the old man by crucifying it to His cross, and cleansing our sin nature completely by taking away our sin. They are not saved, but Jesus will say to them, I never knew you. Matthew 7:21-23.
