Eph 2:8-9 8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: 9 Not of works, lest any man should boast. The bible teaches and from this very passage, the doctrine of Salvation by Grace excluding any merit or works, or conditions and requirements to be performed on the part of man to secure it. Once a condition has been set, any condition, in order to get saved, something man must perform, such as to believe, to repent or anything else, Salvation by Grace through Faith is denied, and a work salvation is erected in its place. Rom 11:6 And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then it is no more grace: otherwise work is no more work. The Main reason why Salvation by Grace through Faith is denied by the religious world is because, Salvation by Grace means Salvation by being of the Election of Grace Rom 11:5-7 5Even so then at this present time also there is a remnant according to the election of grace. 6And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then it is no more grace: otherwise work is no more work. 7What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded. You see,Salvation by Grace means that God hath only purposed to save only some out of lost humanity by Grace and to dam and confirm in blindness the rest !
