There is no point in this life where it will not be appropriate to exhort the saints to the life of Bible sanctification. I think it meet, as long as I am in this tabernacle, to stir you up by putting you in remembrance . . . And as long as we are in this tabernacle, we will need to read what Peter says about sanctification. This fact presupposes that in this life we will never arrive at a sinless state, for sinless creatures, being fully sanctified, have no need of the doctrine of sanctification. For them a very large portion of the Bible would be irrelevant.
Sanctification is glory in the seed, and glory is sanctification in the flower.
None of the prophets or apostles claimed to be without sin. In this life there is no stopping place, no point to which we may come and say, I have fully attained. The law of God still stands to demand a holiness greater than any saint has to give. The basic, inescapable fact that sanctification is always called for in this life, that the process must continue until glorification, is sufficient to cut off all aspirations of perfectionism. It is the strangest anomaly that some Christians who practice the ordinance of footwashing in conjunction with the Lord's Supper have been the most prone toward the doctrine of perfectionism.
