If we think we can even flirt with pornography or violations of chastity or dishonesty in any form and not have it negatively affect us and our families, we are deceived.

 I may not have the ability of Elder Jeffrey R. Holland when he spoke in a priesthood session a few years ago to “get in your face … , nose to nose, with just enough fire … to singe your eyebrows” (“We Are All Enlisted,” Ensign or Liahona, Nov. 2011, 45); but, dear brethren, we need to wake up to how commonly accepted practices in the world choke our power in the priesthood. If we think we can even flirt with pornography or violations of chastity or dishonesty in any form and not have it negatively affect us and our families, we are deceived. Moroni stated, “See that ye do all things in worthiness” (Mormon 9:29). The Lord powerfully directed, “And I now give unto you a commandment to beware concerning yourselves, to give diligent heed to the words of eternal life” (D&C 84:43). If there are any unresolved sins preventing our worthiness, we need to change.

The Essence of Holding the Priesthood is to Magnify Our Calling

Receiving the priesthood and its various offices should mean something to us. It should not be a perfunctory “rite of passage” that automatically happens at certain ages but a sacred act of covenant thoughtfully made. We should feel so privileged and so grateful that our every action shows it. If we seldom even think about the priesthood, we need to change.

We need to serve! The essence of holding the priesthood is to magnify our calling (see D&C 84:33) by serving others. Avoiding our most important duty to serve our wives and children, not accepting or passively fulfilling callings in the Church, or not caring about others unless it is convenient is not who we should be.

Never Let An Earthly Circumstance Disable You Spiritually

If you feel you have been wronged—by anyone (a family member, a friend, another member of the Church, a Church leader, a business associate) or by anything (the death of a loved one, health problems, a financial reversal, abuse, addictions)—deal with the matter directly and with all the strength you have. “Hold on thy way” (D&C 122:9); giving up is not an option. And, without delay, turn to the Lord. Exercise all of the faith you have in Him. Let Him share your burden. Allow His grace to lighten your load. We are promised that we will “suffer no manner of afflictions, save it were swallowed up in the joy of Christ” (Alma 31:38). Never let an earthly circumstance disable you spiritually.
