Eph 2:4 ¶ But God, being full of mercy, through the great love which he had for us,
5 Even when we were dead through our sins, gave us life together with Christ (by grace you have salvation),
6 So that we came back from death with him, and are seated with him in the heavens, in Christ Jesus;
7 That in the time to come he might make clear the full wealth of his grace in his mercy to us in Christ Jesus:
8 Because by grace you have salvation through faith; and that not of yourselves: it is given by God:
9 Not by works, so that no man may take glory to himself. 10 For by his act we were given existence in Christ Jesus to do those good works which God before made ready for us so that we might do them.
All you can do is all you can do; but all you can do is enough!
