The scriptures tell us that according to the law of Moses without the shedding of blood there is no forgiveness or remission of sins.
The KJV uses the word remission which is more than just forgiveness. It means to be set free from sin and its consequence.
Remission in the Greek, is aphesis, which means forgiveness, deliverance and liberty. To not only be forgiven (letting go as if they had never been committed), but to be released from the bondage or imprisonment of the penalty for sin.
Sin has consequence. Under the law, a life must be given up for a life. The soul that sins shall die. Romans 6:23
Jesus, who was without sin, gave his life up for the sinner who repents and forsakes their sin. Repentance is a big factor in the remission process. Without repentance there is no forgiveness of sin. In order to receive this remission of sin, one must repent.
Without repentance, there is no remission of sins. Acts 2:38
Repent and be converted, that your sins may be blotted out. Acts 3:19
Repentance Metanoeo in the Greek is to have a change of mind for the better. To turn from sin or breaking God’s laws. To be converted to God’s word. That is to receive the gospel’s truth.
But your iniquities have separated you from your God; your sins have hidden His face from you, so that He will not hear. Isaiah 52:9
Sin has consequence. It produces death. Not just eternal death but death as in no life of God. It separates us from God. He does not hear prayer, we lose our joy, and we can become fearful, sick and weak.
Do not be deceived: God cannot be mocked. A man reaps what he sows. Galatians 6:7
The one who sows to please his sinful nature, from that nature will reap destruction. Galatians 6:8
He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy. Proverbs 28:13
As many as I love, I rebuke and chasten: be zealous therefore, and repent.
Scriptures tell us that it is FAITH IN THE BLOOD that saves from the penalty of sin. When we repent and turn to the truth of the gospel we must have faith in the blood of Jesus Christ for forgiveness of sin.
Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; Romans 3:25
We cannot save ourselves by good works or good deeds.
Romans Chapter 3 tells us that under the law we all are condemned to die eternally because of sin. Unless we turn to Jesus Christ for the remission of our sin.
Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God. Romans 3:25
Once we are forgiven by repentance and faith in the blood of Jesus Christ then we are made righteous before God as if we have never sinned.
For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him. Romans 5:21
And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith: Philippians 3:9
If we confess our sin to God, repent of our sin and have faith in the Blood of Jesus Christ we can be forgiven and made righteous by God as if we have never sinned.
If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. John 1:9
