The Commandment to Love

"Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.
This is the first and great commandment.
And the second is like unto it, Thou shalt love thy neighbour as thyself." (Matt 22: 37-39)

As proclaimed in this verse, many of the teachings of Christ encourage the love of god and the love of others, which is the “first and great commandment." Another scripture that builds on this commandment is found in 1 John 4:20-21. “If a man say, I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen, how can he love God whom he hath not seen?...And this commandment have we from him, That he who loveth God love his brother also.”
In other words, if we are to truly be lovers of God, then we must also love our brethren around us, or all people, just as God loves all people. So, to be the people of God and to show how much we love Him we must serve and care for others, even if they are not as kind and loving towards us as they could be. I personally believe that when we love others as Christ would love them, then we are doing His work, and even the most hard-hearted of people can change for the better from our love.
I think Heavenly Father is definitely sad with the propagation of hatred and cruelty that his children so easily treat each other with. However, though it is natural to be spiteful and unkind, I believe that when we are instead loving and kind as God wants us to be, then our love will replace the hatred in people's hearts.
This outpouring of love that "spreads abroad in the hearts of men" has the potential to change the world into a bright place.

Choosing to be Faithful (Hebrews 11)

In Hebrews 11, there is a magnificent sermon on the power of faith and how the faithful have been blessed since creation. Paul names multiple religious celebrities such as Noah and Moses and how their faith brought to pass miracles. Faith precedes miracles, and show that the Lord is pleased with us. It's certainly true that the natural man is rebellious, and it is very easy to give into the temptation to ignore the instructions of God. However, we must not do that! The counsel of the Lord helps us to conquer the darkness in our lives and minds, and put out the "fires" of sin that we started from ignorance. God will always be willing to give us counsel so long as we are willing to turn from the natural man and listen. We must show a change of heart, and turn our rebellion into faith. If we want to please the Lord, then we must believe and have faith in Him.
 I for one want to please the Lord. So, it is crucial that I am always building my faith and remaining faithful, and referring to the examples of the people in the scriptures is always a great place to learn how to improve my faith.
Christ is one of the many examples we can build our faith from, and there are many powerful hymns on living by Christ's example of faith. If anyone was truly faithful during mortality, then Christ was, and by his life so many people also learned to be faithful. He helped those who were struggling, and just like you said, we should also do the same.
When we show our love and faith in the Lord and live by the examples of the righteous, then God will also bless us even in the midst of adversity. It can be difficult to accept or even acknowledge the Lord's chastening, as the natural man wants to flee from anything that damages his/her pride or reveals hidden shame and guilt. However, when we open up to the Lord and fully listen to and accept the chiding of the Lord then we will be humbled and have the unpleasant feelings of guilt and shame washed away. The Lord chastens us because he loves us, and because he wants his children to return to his side. As such, we should not only have the faith to live by the Savior's example, but to have the faith to accept when we have done wrong and so be able to listen to the words of the Lord.
