My mother-in-law once asked if I believed that life was just a love story. LOL I have to say I think I took her back a little when I said yes. I explained that as children we are taught to love our neighbors and serve others. We gain friends and feel sad when others do not like us. The commandments talk of love too Love the Lord they God with all they heart, might, mind, and strength. Love they neighbor as thy self. The Savior says "If ye love me keep my commandments."
As we grow many of us learn to love our families more and they find the special someone to share the eternities with. That is another love story. ;) Then we have children of our own and a new chapter of love begins and you learn to love your spouse even more and your child always take your breathe away when you look at them and remember where they came from and you are technically just borrowing them, but they are still yours. You made their physical bodies. Such miracles.

"Love one another as I have loved you." Christ suffered 3 times for our sins 3 times!! He knows exactly what  we are going through if only we will let Him lead us through the darkness. I had a thought about when He said "Father why hast Thou forsaken me." Christ had to know what we feel when we no longer have the spirit with us and how agonizing it is. Christ did everything for love. So yes life is a love story. :)
