Do you believe that Jesus is able to do all that needs to be done for your salvation?Do you entrust the weight of your salvation unto Him? If you do, then it is Christ (not your faith in Christ) that does all the work. Your faith neither ADDS TO nor AIDS IN the work of Christ. Your faith merely RESTS and RELIES UPON the work of Christ. Salvation is completely by grace, even the faith by which we take hold of his promises is His gift to us. Therefore, our salvation & the faith by which we receive salvation come from the Grace of God.
