Before you read any more further, know that Jesus Christ died for our sins according to the Scriptures. By keepigg this in mind, read further and know that without Christ we have no the smalest chance to overcome the Sin; without Jesus we are doomed to destruction and no matter how good we are, we are helpless sinners. Apart from God's provided way which made us free from sin and its power, who redeemed us from the curse of the law, we are dead and lost in our transgressions and we are sinful creatures on whom God's wrath rest, no matter how high moral life we lead.
How can we know we sin?
First and the most important thing to know is that we Sin, if we live apart from God or deny Him by no matter what reason. To deny God and live without Him is the greatest sin of all sins.
Next, we can know it by Ten Commandments which God gave to Moses. Ten Commandments are given to us to know the Sin, what that is; to know and understand that no human being is able to fulfil or keep them on their own. If there could be no law we could not know the sin (Romans 7:7). So, Law shows us the Sin in us.
God says: “do not do” or “do it that way.” God's given law to Moses are saying "you shall not, you shall not......" If we disobey His law and do opposite than we commit sin. Apart from Christ we are doomed in our sins and transgressions, and we have no the smalest chance to receive forgiveness and way to heaven. Our conscience also shows us what is good and what is bad and confirms that God's given laws are good and right.
Further, the Hebrew word for sin is chattath and means offense. If we do opposite the Word of God we offend Him. Sin is everything what is done and thought apart from God and against Him. Sin is rebellion against God. Sin is evil from itself. Sin is pride and vainglory. Sin wants to be like God. People sin every time when they decide they are smarter like God and can go on without Him.
“Everyone who sins breaks the law; in fact, sin is lawlessness” (1 John 3:4).
Sin, disobedience to God, killed our first parents. Although their bodies moved, although their emotions and feelings were at work within them, they were dead because their spirit died. Dead spirit can not be united with the living Spirit of God.
Sin brings fights, wars, hatred, bitterness and malice. Sin destroys absolutely all good things and brings calamities, disorders and disasters. Sin controls, manipulates and dominates. Sin brings fear, pain, sufferings and keeps people in darkness. Sin makes unconscious, sin blinds and leads to believe in lies. Sin violates, pollutes and defiles all what is good. Sin controls humankind and keeps people to be cruel, merciless and insensible. Sin destroys everything. Sin makes habits and kills the Truth. Sin covets, lies and slanders; sin abuses and misuses. Sin kills relationship, sin kills love and leads to death. Sin breaks, destroys…
But He hears us always when we call to Him for forgiveness and wilingness to return to Him.
Sin is our heart’s normal condition (Romans 3:10-18) and without Christ we are dead in our transgressions (Ephesians 2:1), but all those who are saved by grace are raised up with Christ and seated with Him in the heavenly realms in Christ Jesus (Ephesians 2:6). Do't you see how close you are to God when saved by grace through faith?
We all must understand that “there is no one righteous, not even one…” (Romans 3:10-18). No person can be good without or apart from God.
But see, “at just the right time, when we were still powerless, Christ died for the ungodly” (Romans 5:6). Now through Him we can have life and peace with God.
“For the law was given through Moses; grace and truth came through Jesus Christ” (John 1:17). Who can now accuse those who are in Christ!?
No one person on this planet is able to keep the law by trying to live absorving them. No one can receive the forgiveness for sins by trying to keep the law, because if a person breaks law just at one point than he is guilty of breaking all of them (James 2:10; Deuteronomy 27:26 ). Anyone who lives by law and tries to do good apart from the atoning blood of Christ is already condemned and lives under the curse.
And all sins can be forgiven by almighty God, but “blasphemy against the Spirit will not be forgiven” (Matthew 12:31-32; Luke 12:10; Mark 3:29). Anyone who sin by denying the only God, Almighty Elohim “will go away to eternal punishment, but the righteous to eternal life” (Matthew 25:46; John 3:36; Daniel 12:2).
Now, all our sins can be forgiven by the blood of Jesus Christ (Ephesians 1:7) for “all have sinned and fall short of the glory of God, and are justified freely by His grace through the redemption that came by Christ Jesus” (Romans 3:23-24).
“God presented Christ as a sacrifice of atonement, through the shedding of His blood--to be received by faith. He did this to demonstrate His righteousness, because in His forbearance He had left the sins committed beforehand unpunished” (Romans 3:25).
Now we thank our holy Father "for He has rescued us from the dominion of darkness
and brought us into the kingdom of the Son He loves, in whom we have redemption, the forgiveness of sins"
