What about the ones you don't even know you've committed???
Well lets see what scripture tells us...
4Or if a soul swear, pronouncing with his lips to do evil, or to do good, whatsoever it be that a man shall pronounce with an oath, and it be hid from him;
when he knoweth of it, then he shall be guilty in one of these.
5And it shall be, when he shall be guilty in one of these things, that he shall confess that he hath sinned in that thing: Leviticus 5:4-6
When you become aware of the sin, then the guilt applies, so all the ones you dont know or of ommission God in his mercy does not hold against us.
David and Solomon make it even clearer........
I acknowledge my sin unto thee, and mine iniquity have I not hid. I said,
I will confess my transgressions unto the LORD; and thou forgavest the iniquity of my sin. Selah.Psalm 32:5
He that covereth his sins shall not prosper: but
whoso confesseth and forsaketh them shall have mercy.Proverbs 28:13
and here we see Daniel in prayer....
20And whiles I was speaking, and praying, and confessing my sin and the sin of my people Israel, and presenting my supplication before the LORD my God for the holy mountain of my God;
21Yea, whiles I was speaking in prayer, even the man Gabriel, whom I had seen in the vision at the beginning, being caused to fly swiftly, touched me about the time of the evening oblation.Daniel 9:20-21
So now lets look in Christs time.......
Matthew 3
1In those days came John the Baptist, preaching in the wilderness of Judaea,
2And saying, Repent ye: for the kingdom of heaven is at hand.
3For this is he that was spoken of by the prophet Esaias, saying, The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight.
4And the same John had his raiment of camel's hair, and a leathern girdle about his loins; and his meat was locusts and wild honey.
5Then went out to him Jerusalem, and all Judaea, and all the region round about Jordan,
6And were baptized of him in Jordan, confessing their sins.
Mark 1
1The beginning of the gospel of Jesus Christ, the Son of God;
2As it is written in the prophets, Behold, I send my messenger before thy face, which shall prepare thy way before thee.
3The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight.
4John did baptize in the wilderness, and
preach the baptism of repentance for the remission of sins. 5And there went out unto him all the land of Judaea, and they of Jerusalem,
and were all baptized of him in the river of Jordan, confessing their sins.
and here we see the people confessed the evil deeds they were doing after being convicted of the truth...
11And God wrought special miracles by the hands of Paul:
12So that from his body were brought unto the sick handkerchiefs or aprons, and the diseases departed from them, and the evil spirits went out of them.
13Then certain of the vagabond Jews, exorcists, took upon them to call over them which had evil spirits the name of the LORD Jesus, saying, We adjure you by Jesus whom Paul preacheth.
14And there were seven sons of one Sceva, a Jew, and chief of the priests, which did so.
15And the evil spirit answered and said, Jesus I know, and Paul I know; but who are ye?
16And the man in whom the evil spirit was leaped on them, and overcame them, and prevailed against them, so that they fled out of that house naked and wounded.
17And this was known to all the Jews and Greeks also dwelling at Ephesus; and fear fell on them all, and the name of the Lord Jesus was magnified. 18And many that believed came, and confessed, and shewed their deeds. Acts 19 11-18
and here Paul makes clear that we need to confess and give account to not a priest or confessor in a booth, but to God...
10But why dost thou judge thy brother? or why dost thou set at nought thy brother? for we shall all stand before the judgment seat of Christ.
11For it is written, As I live, saith the Lord, every knee shall bow to me, and every tongue shall confess to God. 12So then every one of us shall give account of himself to God.Romans 14:10-12
and the verses go on and on that we need to confess our sins and repent of them and turn them over to Christ to be cleansed of them......
1 John 1:9
If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
But some Christians rather hold on to them and insist they are not sin, so what happens then when they are judged......
