Repentance did not come by the law

Repentance did not come by the law; it came by grace. Repentance came by the gospel.

In the link to his article in 1688, Thomas Watson said: " .. .. Repentance is a pure gospel grace. The covenant of works admitted no repentance; there it was, sin and die! Repentance came in by the gospel. Christ has purchased in his death—that repenting sinners shall be saved. The Law required personal, perfect, and perpetual obedience. It cursed all who could not come up to this: "Cursed is everyone who does not continue to do everything written in the Book of the Law" (Gal. 3:10). It does not say, "he who obeys not all things, let him repent" —but, "let him be cursed." Thus repentance is a doctrine that has been brought to light, only by the gospel .. .. "

Under the law, we (everyone) who did not obey all that were written in the Book of the Law were cursed. But today under the New Covenant, we (everyone, including those who did not obey the Law) can be saved from the cursed of the Law. This is possible only by repentance (bearing fruit) in Christ.
Luk 13:5-9 KJV  I tell you, Nay: but, except ye repent, ye shall all likewise perish.  (6)  He spake also this parable; A certain man had a fig tree planted in his vineyard; and he came and sought fruit thereon, and found none.  (7)  Then said he unto the dresser of his vineyard, Behold, these three years I come seeking fruit on this fig tree, and find none: cut it down; why cumbereth it the ground?  (8)  And he answering said unto him, Lord, let it alone this year also, till I shall dig about it, and dung it:  (9)  And if it bear fruit, well: and if not, then after that thou shalt cut it down.
