TDG 145.4
(This Day With God 145.4)
Earnestly and untiringly we are to strive to reach God’s ideal for us. Not as a penance are we to do this, but as the only means of gaining true happiness. The only way to gain peace and joy is to have a living connection with Him who gave His life for us, who died that we might live, and who lives to unite His power with the efforts of those who are striving to overcome. (TDG 145.4) MC VC
