If a person is still continuing to do aveiros, is there any sense in doing teshuva?
Absolutely! And he should ask Hakadosh Baruch Hu for help that he should stop. I'll explain that. When a person does an aveiro and he's happy with it, then it's a much greater sin. If a person does an aveiro, but he is ashamed and he's sorry that he's doing it, it's subtracted from his punishment. Yes, even though he still does it.
The Chofetz Chaim, zichrono l'ivrocha, wrote a sefer for Jewish soldiers. In those days when they were drafted into the Russian army they had to eat treifa foods. So he said, “If you must eat treifa food then don't suck the juice out of the bones.” Which means, don't show that you enjoy it. You're only eating it to save your life from starving. And so when a person does a chet, a sin, even a big chet, a mechalel shabbos, but he's sorry he was mechalel shabbos, it's already a madreiga. To be sorry is a madreiga, you have achieved something. Of course it's not teshuva sheleima, very far from it, but it's a very big thing. Haoseh aveiro umisbayeish bo, he's ashamed, it's a very big thing.
And therefore it pays even for sinners to ask Hashem to forgive them. Only they should add, “…and please Hashem help me that I should make a real perfect teshuva.”
