Love bears all things, believes all things, hopes all things, endures all things. Love never ends. As for prophecies, they will pass away; as for tongues, they will cease; as for knowledge, it will pass away.
(1 Corinthians 13:7-8)

That means God loves us constantly, no matter what. It also means we are called to love Him and others in the same way. Real love is eternal and unconditional. Every time we sin, we turn away from that constant, undying light that is God's love. We must turn around and face that light again. We need to convert our hearts and be in love with Him.
