President Monson spoke of the rapidly-evolving moral compass of society and about how, "behaviors which once were considered inappropriate and immoral are now not only tolerated but also viewed by ever so many as acceptable." He continued, "Although the world has changed, the laws of God remain constant. They have not changed they will not change."
The reason that we are not to conform to the teachings of society but cling to the teachings of Jesus Christ is so that we will be better equipped to deal with the storms of life, to learn from them, and to overcome them. By striving to have the gospel of Jesus Christ at our core and the love of the Savior in our hearts, we can effectively deal with all the challenges we face. The constancy of the Lord is, "something on which we can hold fast and be safe, lest we be swept away into uncharted waters." When we live in the world and not of the world, we stay clean and worthy of the influence of the Holy Spirit that we may receive strength from the Lord. "There is nothing which can bring more joy into our lives or more peace to our souls than the Spirit which can come to us as we follow the Savior and keep the commandments."
I know that the Lord hears and answers our prayers. I know from personal experience that only when I am striving to do what the Lord asks am I able to recognize and have the strength to heed His promptings. He is the way, the truth, and the light and the source of the greatest happiness and joy.
