Why is there a need of salvation?

Answer 1

10As it is written, There is none righteous, no, not one: 11There is none that understandeth, there is none that seeketh after God. 12They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one...20Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin. 22Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference: 23For all have sinned, and come short of the glory of God; 24Being justified freely by his grace through the redemption that is in Christ Jesus: 25Whom 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; 26To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus.
