Need love or gift love?

Lewis classifies human loves into two types: need love and gift love, and it made me wonder, is our love for God gift love or need love? In a sense, it should be gift love. We die to ourselves to serve God and obey his commands. We accept his love and allow it to transform us. Loving God requires sacrifice-- sacrifice of our earthly nature and sinful desires. In that way, it seems like a gift love. On the other hand, our souls long for relationship with God. As we love God, we receive the hope of his salvation and redemption of our lives. In that sense it is a need love. We can't love God without being blessed in some way, whether it be spiritually or physically. But do we just love God so that we can receive his blessings? Lewis depicts need love as love that is more focused on self than on the object that is being loved. I think we love God because God is worthy of our love. The Bible says we love Him because he first loved us. But we also need God, and while we may strive to give ourselves in selfless devotion to God in honor of Christ's sacrifice for us, we can't deny the fact that we need God and we benefit from loving Him. So maybe you really can't classify our love for God as one type of love or the other.
