It is even more plain here:
1 Corinthians 15 1. Now, brothers and sisters, I want to remind you of the gospel I preached to you, which you received and on which you have taken your stand.
2. By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain.
3 For what I received I passed on to you as of first importance[a]: that Christ died for our sins according to the Scriptures,
4 that he was buried, that he was raised on the third day according to the Scriptures,
The Gospel is the Death, burial and resurrection of Jesus Christ. Paul further explains here:
Romans 10:9 If you declare with your mouth, “Jesus is Lord,” and believe in your heart that God raised him from the dead, you will be saved.
and here is Jesus explaining it before Paul
John 3:16 For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
I see no mention of the Torah.
Thank-you God Bless.

The problem many have is that they mistake “belief” as the apostles preached it with simple intellectual belief in the truth of those statements. But John raised that standard much higher in his first epistle, to doing the things he did for the same reasons that he did them.
That is a much higher level than most will ever be willing to mount, thus the narrow path.
