Through his prophet Alma, Jesus Christ taught:
And he said: Thus saith the Lord God—Cursed shall be the land, yea, this land, unto every nation, kindred, tongue, and people, unto destruction, which do wickedly, when they are fully ripe; and as I have said so shall it be; for this is the cursing and the blessing of God upon the land, for the Lord cannot look upon sin with the least degree of allowance. (Alma 45:16)
We know that God loves us. And so he must possess the virtue of tolerance to a degree that we do not. But from this passage we learn that there must be things he does not tolerate. What are they?
God does not tolerate sin. Why? It is because he loves us. Sin causes us pain. It injures us. It brings failure and disappointment. Ultimately it destroys us. We should not marvel that Jesus Christ is intolerant when it comes to sin. He is intolerant because he loves us. He wants us to be happy, and he knows better than any of us where the path is that leads to happiness. Hence, Jesus Christ loves us, but he is intolerant of our sins. We must repent of them or we will suffer.
