I think because it is God who does soften our hearts when we do receive his rest from us trying to work to get ourselves saved and staying saved. (Hebrew 4)The righteousness is one imputed to those who can rest . "It is God" who works in us to both will and do His good pleasure. Whether this in when we maintain keeping the commandment or when we fail and he calls us to repent.
We are to do all things without murmuring of those who we think they do not receive His rest freely with no cost on our behalf. According to Hebrews 6 He will not forget the goods works we do perform towards His name. We do have that power of Christ working in these bodies of death but it are not of us.
Things can get confusing when men think the reward will be different for each of us. The reward is redemption. The better thing that accompanies him working in us.
