Salvation is by grace, by faith, and by Christ alone. We are not good enough to earn salvation, and never will be. Christ alone is good enough. Neither can we say that salvation is Jesus plus . Salvation is not law and grace.
Salvation is grace.
We must not delude ourselves into thinking that we can earn anything from God. We are not equipped to do so, for we are imperfect humans and will fail time and again. Even the old covenant noted that all our human righteousness is but filthy rags. This of course does not mean that we are free to behave in any way that we want, or in fact that we will, if we authentically accept Christ as Lord and Savior, even want to. He will produce works in us that will cause others to come to Christ.
