We don't continue to sin until Jesus returns. We must have complete victory through Jesus, by the close of probation.

When He comes He is not to cleanse us of our sins, to remove from us the defects in our characters, or to cure us of the infirmities of our tempers and dispositions. If wrought for us at all, this work will all be accomplished BEFORE that time. When the Lord comes, those who are holy will be holy still. Those who have preserved their bodies and spirits in holiness, in sanctification and honor, will then receive the finishing touch of immortality. But those who are unjust, unsanctified, and filthy will remain so forever. No work will then be done for them to remove their defects and give them holy characters. The Refiner does not then sit to pursue His refining process and remove their sins and their corruption. This is all to be done in these hours of probation. It is NOW that this work is to be accomplished for us.
