We are forgiven of all our sins. Not some but all. We received it at the point of salvation.
who bought our freedom with his blood and forgave us all our sins. Colossians 1:14 TLB
Allow me to illustrate this perfect forgiveness. When I was a youth I went to a local Veteran's Parade. To get a better view, we went to the top floor of a parking garage. From this view, I could see the beginning to the end of the parade. When I received Christ, He saw my life from start to finish. He washed me in that precious blood and declared my life forgiven.
We stand inside of time, God isn't constricted by time. He has already seen our whole life, and when we receive His free gift He declares us forgiven once for all time. Apologies, confessions and turning away will not make us receive more forgiveness. I will concede that acknowledging our errors or poor choices and plain sins to our Father is healthy and helps us mature. However, it should never be done to receive forgiveness or because we think God is mad and holding something against us.
Grace isn't a half measure. Salvation and redemption don't come with stipulations. Forgiveness isn't borrowed on an installment plan. Our relationship with God has no strings attached.
Salvation and our walk with God aren't like a game show prize. Winning a new car sounds great. It's free. However, once you partake of the prize, you're now responsible for the insurance, which can be pricey depending on the vehicle. You also are put under a tax burden for the price of the car. God's goodness comes with no strings attached and adds no sorrow.
Religious grace offers a free gift with many strings attached. Forgiveness is for your past sins only and must be received again and again or you will be under bondage of sin and unforgiveness. Your salvation once freely received now has maintenance requirements that if you don't meet means you forfeit it. This isn't the Good News!
In summation, in Christ, we are forgiven and made righteous and set apart by faith once for all time when we receive His free gift. We are forever forgiven. In Him, we are forgiven of all our sins. Our past is cleansed and done away with in Christ.
Our present mess ups are already dealt with and He holds our future in His hands. We have hope because He has already cleansed us, made us righteous and forgiven us and set us apart once for all time. This is the Good News of the Gospel of Jesus Christ! Reject and relinquish the fake news of tradition concerning your once for all total forgiveness in Christ.
