Is Nama Sankirtana is by itself sufficient to remove all our sins?
Nama sankirtanam removes the indifference we have towards bhagavan, his devotees and the spiritual concept of Life, it provides us with the mental strength, power of endurance and a clear frame of mind to make us qualified to begin Varnasrama Dharma(Karma Yoga)-->by which Bhagavan becomes pleased--> hence he removes all our papa,punya and takes us back to his spiritual abode(Vaikuntha).
Say for a Kshatriya, Nama sankirtanam gives us all basic qualifications a kshatriya needs to defeat the allies of Adharma and establish Dharma. Endowed with all basic qualities unless a kshatriya fights the war(which is his Karma Yogam), his enemies cannot be defeated, similarly endowed with all auspicious qualities, unless one executes his Karma Yogam-->Bhagavan will not remove his eternal enemy which is nothing but his papa and his punya.
Unless one is purified of these misgivings(papa,punya) one will not be able to go back home back to Godhead(Vaikuntha).
