It seems ridiculous to talk about training in love. We all know what it is, we all know how it goes. Well, true and false. We all know what the emotional aspect of love looks like, but as a fallen people we rarely live out what the emotional aspect calls for.
We all know, intellectually, that love is a movement of will, not merely an emotion. Love can act without an emotion necessarily being attached. More importantly, one of the tremendous pieces of doctrine that St. Thérèse of Lisieux left with us is that love without works is dead. This is a natural outgrowth of the understanding in the Letter of James that faith without works is dead. Faith, Hope, and Love grow together or die together. When one is supported and nurtured, all three thrive. That is why love is so important in approaching God. Love causes faith to thrive and gives birth to new hope that sustains us through the long languors of love.
Training in love seems a good idea. How do we begin to love God passionately if we do not already do so?
Pardon a brief digression here. Wittgenstein is reported by some to have intimated that words shape reality. I do not know if he actually said this, but if it is true, the man obviously needed a psychiatrist. Reality is. The Ground of Being that reifies all that is, is unchangeable, so too the reality built upon His constant attention. That is not to say that things do not change, but that reality is and is discernable and understandable to some extent to the human intellect. (Good thing Wittgensteinian disciples didn't promulgate their nonsense until after we had a firm foundation in the sciences.) At any rate, words do not shape reality. However, they do shape our perceptions of reality. How we talk about or describe something shapes our feelings about that thing. How we talk about or to a person shapes our feelings about the person. Talk is not everything, but it is a powerful way to shape perception. (Hence, part of James's further admonition to "bridle the tongue.")
So my first suggestion for training in love is to change or enhance the way we talk to God. In addition to formal written prayers or spontaneous prayer it might be good to add to our daily routine a litany of thanksgiving. Perhaps the first prayer in the morning could start with a line from Psalms--"This is the day the Lord has made, let us be glad and rejoice in it." From there we could move to a simple litany of thanksgiving, being mindful of the presence of God in morning ablutions and preparations. We thank Him for our own being, for another day, for our spouses and children (if any), for our lack of spouses and children (if we lack them), for our material goods, for our health, and then we move on to thank Him even for the challenges of the day--poor health, difficult tasks, even worries. We hand them all over in thanksgiving, knowing that He will support us through them all. The litany of thanksgiving puts us in the mindframe to be grateful and to perceive God's hand in the events of the day. A very wise Jesuit once said, "A grateful heart finds it hard to be unhappy." And a happy heart finds it easier to love the Person who gave it so much happiness.
Thus my first suggestion--start the day with a litany of thanksgiving. Everything you can think of to praise and thank God for say or sing in your own private litany. Thank Him for all that you have, all that you are, and all that is around you. Thank Him for being present to preserve it all. Thank Him for the guidance He gives and the love He pours out.
Perhaps this starts as mere words, but as the practice develops and continues it grows into a yearning to do something to express thanksgiving, to share with others the fantastic joy of knowing God. This is a first step in the dance of love. We are moved to do something, however small, however seemingly meaningless. We are moved to DO something beautiful for God.
