You Are Forgiven
You are Already Forgiven: The sins of all people for all time have 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 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 on the Cross was only potential, and you must activate, or appropriate, it by repentance and faith is not found anywhere in Scripture. Forgiveness is not "salvation." Faith and belief are necessary to be saved; only those who trust Jesus Christ as their Savior share His eternal life. God forgave everyone but gives new life to those who trust His Son (1 John 5:12). (See below to read about the one and only unforgivable sin.)

The Unforgivable Sin: The Sin of Unbelief
The Holy Spirits convicts the world of its unbelief. Since eternal life is found only in Jesus Christ, rejecting Jesus is the same thing as rejecting His eternal life. 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 (Hebrews 8:12). It is your own conscience or a religious system that leads to feelings of guilt and remorse.
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; ...
If you reject Christ, you reject the eternal life that is found only in Him (1 John 5:12b). If accept Christ, He will teach you and He will give you the understanding of what He has done for you personally. And, He will show you that living by faith is living by the power of Christ in you. You may face difficulties in your life, but Christ will guide you through because you are, now and forever, His friend and a member of His family.
