You Are Forgiven
You are Already Forgiven: The sins of all people for all time have already been forgiven because Jesus Christ died for every single person, including you. Forgiveness happened on the Cross of Christ, not after as many teach. The Bible clearly says that without the shedding of blood there can be no forgiveness (Hebrews 9:22). Christ shed His blood one time on the Cross and because of this all, including you, are forgiven. The Bible does not teach any other time or any other way that sins can be forgiven (Hebrews 10:18,12; 7:27b).
The notion that forgiveness is only potential, something you must "appropriate" by repentance and faith, is not found anywhere in Scripture. Nor is there any Biblical foundation for confessing sins day after day as is commonly practiced.
Forgiveness is not "salvation" as many believe. Even though all are forgiven, faith in Christ as Savior is necessary to be saved; only those who believe are given a new heart indwelled by the eternal life of Jesus Christ. God forgave everyone but gives new life to those who trust His Son (1 John 5:12).

The Unforgivable Sin: The Sin of Unbelief
The Holy Spirits convicts the world of its unbelief.
John 16:8-9a "And He (Holy Spirit), when He comes, will convict the world concerning sin, and righteousness, and judgment;  concerning sin, because they do not believe in Me; ...
Since eternal life is found only in Christ Jesus, rejecting Jesus is the same thing as rejecting His eternal life (1 John 5:12b); this is why unbelief is the one and only unforgiveable sin.
Also, and very important, the Holy Spirit does not convict you of your individual sins since God has already forgiven and forgotten all your sins. It is your own conscience or a religious system that leads to feelings of guilt and remorse.
