There are our pure love for God and our impure love for ourselves. It's easy to let our selfish love which shouldn't be there in the first place override our love for God. For example, we personally dislike someone. We know that we should love that person, yet we decide not to have anything to do with that person. On the other hand, we can like someone for selfish reasons, so under the pretense of loving God, we "love" that person. In both instances, we are being hypocritical. To love as God loves, we must ground ourselves solidly in the Lord and vanquish all our selfish motivations. Unless you already know the Lord intimately, this can be a tough battle to fight. God bless you all!
