Context: When a person tells others “Be good”, he conveys to his hearers the feeling that he is good and they are not. When he says “Be brave, honest and pure”, he conveys to his hearers the feeling that the speaker himself is all that, while they are cowards, dishonest and unclean.
To love God in the most practical way is to love our fellow beings. If we feel for others in the same way as we feel for our own dear ones, we love God.
If, instead of seeing faults in others we look within ourselves we are loving God.
