This morning I was reading in 1 John 4.
20 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 I was reminded of Paul's teaching to the Corinthians in 1 Corinthians 13 all about charity. If we have not charity we are nothing. In other words, if we are not long-suffering, patient, slow to anger, kind, endure all things, etc. we are nothing before God. You can give to the poor all day long but if you don't feel love for people it doesn't help your case. You can call yourself Christian until the cows come home but it won't make a dime's worth of difference if you do not have the love of God in your heart for your fellow men.
This is a tall order. It is difficult to love our families all the time, let alone strangers, let alone people who have done us wrong! But that doesn't mean it is right to walk away from this commandment to "love one another as I have loved you" which Christ taught. And it certainly doesn't mean it's OK to take the law into your own hands. "Judgement is mine," God says. We will answer for our own sins and other people's sins really aren't our concern anyway unless they do us harm.
President Dieter F. Uchtdorf, the second counselor in the First Presidency of the LDS Church gave a sermon during April 2012 General Conference titled, "The Merciful Obtain Mercy." This part I quote is from towards the end.
What a terrific lesson and reminder.Brothers and sisters, there is enough heartache and sorrow in this life without our adding to it through our own stubbornness, bitterness, and resentment.We are not perfect.The people around us are not perfect.19 People do things that annoy, disappoint, and anger. In this mortal life it will always be that way.Nevertheless, we must let go of our grievances. Part of the purpose of mortality is to learn how to let go of such things. That is the Lord’s way.Remember, heaven is filled with those who have this in common: They are forgiven. And they forgive.Lay your burden at the Savior’s feet. Let go of judgment. Allow Christ’s Atonement to change and heal your heart. Love one another. Forgive one another.The merciful will obtain mercy.
