I’ve got that joy. Do “you greatly rejoice”, and “delight with inexpressible and glorious joy”? You can. But “you must be born again” (Jesus said).
The very clear message of Christ is that sinners can be changed when they repent in sincerity and truth, choosing to become God’s true followers. You can have all your sinful past forgiven by God, and be totally accepted into His Forever Family immediately, both here on earth now – and in heaven where we are declared forgiven in His Courts. Don’t be fooled into hell by thinking your sin is legitimate before God.
