faith is the only way.

"...now the righteousness of God without the Mosaic Law is manifested, being witnessed by the Law and the prophets;

even the righteousness of God which is faith of Jesus Christ unto all and upon all them that believe: for there is no difference:

for all have sinned, and come short of the glory of God;

being justified freely by his grace through the redemption that is in Christ Jesus:

whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God;

to declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jeus."

-Romans 21-27.  King James Version
