As any lost gentile, yes. An observant Jew, however, is still under the Old Covenant which God made with Moses which is not repealed. God’s covenant remains.
Jeremiah 31 Behold,the days come,saith the LORD, that I will make a new covenant with the house of Israel,and with the house of Judah:32 Not according to the covenant that I made with their fathers in the day that I
took them by the hand to bring them out of the land of Egypt; which my covenant they brake,although I was an husband unto them,saith the LORD:33 But this shall be the covenant that I will make with the house of Israel; After those days,saith the LORD,I will put my Torah in their inward parts,and write it in their hearts; and will be their G-d,and they shall be my people.34 And they shall teach no more every man his neighbour, and every man his brother,saying,Know the LORD: for they shall all know me, from the least of them unto the greatest of them,saith the LORD: for I will forgive their iniquity,and I will remember their sin no more.
Only one way their is forgiveness of sin... shedding of blood... His only begotten Son took all of our placev. the new covenant is here and now.. To the Jew first and also to the Gentile. Believe and be baptized in His Son’s name for the remission of your sins and you will receive the gift of His Holy Spirit.... and His law will be written on your heart..
