This subject is so confusing. To myself, all of them are missing the mark, which of course is "sin". I just cannot seem to separate them. @1stCenturyLady seems to have a handle on this, I just cannot seem to separate them.
And then, there is "trespasses"...
Willful sins based on our sin nature are what we were cleansed from initially, including the source of those willful sins, our SIN NATURE OF THE FLESH. Those are sins of lawlessness. Jesus took the desire to commit those type of sins away.
1 John 3:4-5
4 Whoever commits sin also commits lawlessness, and sin is lawlessness.
5 And you know that He was manifested to take away our sins, and in Him there is no sin.
Those are sins unto death that were cleansed out of us. They are willful sins against the moral laws of the Ten Commandments, namely the last 6.
Revelation 21:8
8 But the cowardly, unbelieving, abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars shall have their part in the lake which burns with fire and brimstone, which is the second death.”
Hebrews 10:26-31
26 For
if we sin willfully after we have received the knowledge of the truth, there no longer remains a sacrifice for sins, 27 but a certain fearful expectation of judgment, and fiery indignation which will devour the adversaries. 28 Anyone who has rejected Moses’ law dies without mercy on
the testimony of two or three witnesses. 29 Of how much worse punishment, do you suppose, will he be thought worthy who has trampled the Son of God underfoot, counted the blood of the covenant by which he was sanctified a common thing, and insulted the Spirit of grace? 30 For we know Him who said, “Vengeance is Mine, I will repay,” [
a]says the Lord. And again, “The Lord will judge His people.” 31 It is a fearful thing to fall into the hands of the living God.
1 John 5:16-18
16 If anyone sees his brother sinning a sin
which does not
lead to death, he will ask, and He will give him life for those who commit sin not
leading to death. There is sin
leading to death. I do not say that he should pray about that. 17 All unrighteousness is sin, and there is sin not
leading to death. 18 We know that whoever is born of God does not sin; but he who has been born of God keeps himself, and the wicked one does not touch him.
Nancy, there is a false doctrine of demons running rampant in the Protestant Church that completely denies the finished work of Christ on this, and declares that "we will always have our sin nature" and why we are constantly in need a Savior. We HAVE a Savior! He abides in us, and we in Him. Satan wants us to reckon ourselves sinners, not free from sin.
Romans 6
6 knowing this, that our old man was crucified with
Him, that the body of sin might be done away with, that we should no longer be slaves of sin. 7 For he who has died
has been freed from sin. 8 Now if we died with Christ, we believe that we shall also live with Him, 9 knowing that Christ, having been raised from the dead, dies no more. Death no longer has dominion over Him. 10 For
the death that He died, He died to sin once for all; but
the life that He lives, He lives to God. 11 Likewise you also,
reckon yourselves to be dead indeed to sin, but alive to God in Christ Jesus our Lord.
Trespasses:
Tresspasses are not against God's moral laws. They are immature fruit, and part of our human nature, not the old sin nature. Even when we are filled with the Spirit of Christ, that doesn't mean we are mature Christians, but God doesn't want us to stop growing. He prunes us.
1 John 1:7
7 But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin.
2 Peter 1:5-9
5 But also for this very reason, giving all diligence, add to your faith virtue, to virtue knowledge, 6 to knowledge self-control, to self-control perseverance, to perseverance godliness, 7 to godliness brotherly kindness, and to brotherly kindness love. 8 For if these things are yours and abound,
you will be neither barren nor unfruitful in the knowledge of our Lord Jesus Christ. 9 For he who lacks these things is shortsighted, even to blindness, and has forgotten that he was cleansed from his old sins.
