Feelings and individuality are over-valued in modern Christianity. But it is possible to feel strongly about Jesus, as a real person, not as an abstract concept. To do that, you have to know who he is — this is best done by reading the gospels, which are in part his biography. This brings you to the same level of affection you might have for Tesla, or Vitruvius, or Archimedes, or whoever your favorite (most loved) dead historical figure might be.

Next, pray and read the Psalms (and pray the Psalms), because they are the words of Jesus, given by inspiration to David et al. This makes you an active participant in the conversation between God and the Church which has been happening throughout the history.

One other great resource for understanding the "loveliness of Christ" is a book by the same name, by Samuel Rutherford. It's sort of a mixture of all of the above, including personal and theological articulations of what Jesus should mean to the Christian. Especially good in seasons of grief, when God can seem most remote, and when Jesus can become most real.
