I did not listen to the clip, but would like to ask you something. After you believed and ask the Lord to forgive you of your sins, were you punished by God in any way for the sins you had committed? When the blood of Christ purged your conscience from dead works associated with sin, did you live in any guilt for the sin that God had cleansed you from? Did the women caught in the very act of adultery, who was brought to the temple before the presence of Christ, get condemned and receive the punishment of stoning for her sin or was she given grace by Jesus Christ and exhorted to go and sin no more?
Didn't Jesus Christ take our sin upon His own body when on the cross, being punished for our sin through the shedding of His own blood and through death, so that when we believed upon Him we might be free from sin and the wages of sin which is death? Didn't Jesus Christ become our substitute and atone for our sins on the cross that we might have life not death? Those that have believed upon Christ will never be punished for any sin because Christ was punished in their place.
If we sin and continue in that sin, He will chasten us as His son until it yields a peaceable fruit of righteousness in this life or if we reject His chastening and He may take us home early through physical death and without dying grace. The sin never took away His imputed righteousness and salvation that was given by grace but we will suffer loss and be ashamed at the coming of Christ. The only thing we experience when we sow to the flesh, is some form of corruption in our soul or body, but this is not punishment but rather a reaping and sowing law of the flesh, it is a form of death but not physical death.
