Being a Son of God, Christ could not not love, as love is the very structure of God. It is not that Christ decides to love; love simply oozes out of his being. “Whoever is without love does not know God, for God is love. God is love, and whoever remains in love remains in God and God in him.” –1 John 4:8,16
All the major commandments of Christ have the word ‘love’ in them. Love God, love thy neighbour, love each other as I have loved you, love thy enemies.
Importance of love as expressed in the remarks of St. Paul and the great poet Dante.
Levels of ‘Love’ and its meanings. Purely a sexual attraction can be, and often is, labeled ‘love.’ Surely, there is a difference in the practical meaning of ‘love’ when associated with sexual attraction or admiration or asking for a favour or submitting to an instruction.
In the teachings of the Christ, we find a very clear hierarchical order: Love from above and obedience from below.
“Whoever keeps the commandments that he has from me is the man who loves me; and the man who loves me will be loved by my Father, and I shall love him and reveal myself to him.” –Christ in John 14:21
