2 Timothy 1:7

7. For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind.

David A. Bednar (October 2007 Conference)

But remission of sin is not the only or even the ultimate purpose of the gospel. To have our hearts changed by the Holy Spirit such that "we have no more disposition to do evil, but to do good continually" (Mosiah 5:2)... is the covenant responsibility we have accepted. This mighty change is not simply the result of working harder or developing greater individual discipline. Rather, it is the consequence of a fundamental change in our desires, our motives, and our natures made possible through the Atonement of Christ the Lord. Our spiritual purpose is to overcome both sin and the desire to sin, both the taint and the tyranny of sin.

Helaman 3:35

35. Nevertheless they did fast and pray oft, and did wax stronger and stronger in their humility, and firmer and firmer in the faith of Christ, unto the filling their souls with joy and consolation, yea, even to the purifying and sanctification of their hearts, which sanctification cometh because of their yielding their hearts unto God.

1 Nephi 2:12

12. And thus Laman and Lemuel, being the eldest, did murmer against their father. And they did murmer because they knew not the dealings of that God who had created them.

John 5:44

44. How can ye believe, which receive honour one of another, and seek not the honour that cometh from God only?

Dieter F. Uchtdorf (April 2007 Conference)

Satan will try to make us believe that our sins are not forgiven because we can remember them. Satan is a liar...God did not promise that we would not remember our sins. Remembering will help us avoid making the same mistakes again. But if we stay true and faithful, the memory of our sins will be softened over time...

Never is the soul nobler and more courageous than when we forgive. This includes forgiving ourselves.

Isaiah 9:6-7

6. For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace.
7. Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even forever. The zeal of the Lord of hosts will perform this.
