So you believe that, according to Paul, he would also preach one is saved by works too, aka carrying the cross?
Paul preach salvation by faith, so does Jesus. And faith mean obey Jesus, and obey Jesus mean cayyy the cross.
Salvation by work can mean to clean our sin by animal sacrifice, pay some money for indulgence etc that's is wrong
Salvation by faith, mean by having faith in Jesus, obey and love Him
If you love Him you must love other, because Bible say if a man say he love God but hate his brother, he is a liar and if you love other, you do help other, not consider work, but you not fell it as a work, as an obidience.
If you love your family and you help them to find a job, you will not consider your action as a work. In grammar stand point it consider a work, but in every day life point of view it not.
