“For as many as are of the works of the law are under the curse; for it is written, ‘Cursed is everyone who does not continue in all things which are written in the book of the law, to do them.'”

for it is written,

Paul quotes Deuteronomy 27:26 to demonstrate the law requires perfection for salvation and sanctification.

‘Cursed is everyone

This second word for curse (“cursed”) is even more intense than the first word for curse in this verse. “Cursed” here carries the idea of loathing by God; people who do not accept His grace stand condemned by God. This is a curse from God, more serious than from man. A “cursed” person is an outcast from God and His heaven. God includes “everyone” in this curse; there are no exceptions. 

who does not continue

The literal idea of “continue” is to remain in. It carries the thought of persevering in something over a period with uninterrupted consistency. No one, except Jesus Himself, has ever lived an uninterrupted life free from sin.

Principle:

The law drives us into the arms of Jesus.

Application:

It is incongruous to insinuate such ideas as “I’m not a sinner. I’m good enough for heaven. My batting average with the Ten Commandments is not that bad.” No one can claim to be free from coveting or selfishness. We have not loved the Lord, our God, with “all” our soul, mind, and heart. The law drives everyone into the outstretched arms of Jesus, who will save poor, lost sinners.
