God chose me to love you because just like Him, He knew I would look pass your faults and see your need. There should never be a time where we, as Christians, should focus on the faults of our sisters and brothers. Doing so would be a misrepresentation of Him and cause shame for the reason Christ died on Calvary. Your faults are none of my business. That is Jesus' business to handle.
God chose you for me to love because loving you shows how valuable you are to Him. Know your worth. He created you in His image. When you look in the mirror, you are looking at a piece of Him. No matter how flawed, He loves you anyway. He loved you so much, He sent Christ to take care of your faults. When Christ ascended back to heaven, He sent people like me to love you with the same measure. Don't worry about those who don't, God gave you just who you need in your life.
The benefit of me loving you the way He told me to is, He is sterilizing you to love others with the same measure. We should always choose love when it comes to others; faults and all. To do the opposite, would be a disservice not only to Him, but also to ourselves.
Love one another. As I have loved you, so must you love one another. - John 13:34
