1 John 4:9-10
I believe that love is only pure if we have the Holy Spirit dwelling in us.
1 John 4:12-13
Christ' love for us demonstrated through His time on earth is the perfect example, the ONLY perfect example, of a pure love. If we want to love as purely as Christ, we have to have Christ in our lives because He will share His heart with us. When someone is saved, we will rejoice! When someone is hurt, we will weep! When someone needs to be loved, we will love! It is only through Jesus.
Put away the world's view on love and ask God for Christ' heart. There is nothing that can compare to the love that Christ has.
