God does not love us because we are valuable.  We are valuable because God loves us.

From John 15:7-11:  “If you abide in me, and my words abide in you, ask for whatever you wish, and it will be done for you.  My Father is glorified by this, that you bear much fruit and become my disciples.  As the Father has loved me, so I have loved you; abide in my love.  If you keep my commandments, you will abide in my love, just as I have kept my Father’s commandments and abide in his love.  I have said these things to you so that my joy may be in you, and that your joy may be complete.”
