"God bids us do what we cannot, that we may know what we ought to seek from him." - Augustine

"To will is of nature, but to will aright is of grace." - Augustine

“Truly, then, we are saved by grace alone, without works or other merit.” - Martin Luther

“Thou must save and Thou alone” - Augustus Toplady
"God knoweth we have nothing of ourselves, therefore in the covenant of grace he requireth no more than he giveth, and giveth what he requireth, and accepteth what he giveth." - Richard Sibbes

Grace is not like a box of candy that you can send back if you don't want it. Grace is divine favor, an attitude of God's own heart. We cannot stop him from loving us, if he chooses to do so. Nor can we stop him from giving us blessings of salvation: regeneration, justification, adoption, sanctification, glorification. His purpose in us will certainly be fulfilled, Phil. 1:6, Eph. 1:11. - John Frame

"If the gospel is grace alone, then every conversion is a miracle." - Tim Keller

"Grace is in no sense contingent upon a condition we meet. If that were the case, it would no longer be grace....It is not by meeting a condition that we receive God's grace. It is by God's grace that we meet His condition. " - John Hendryx
