Love isn't a feeling. It can come WITH a feeling. But really it is a set of actions. 1 John 5:3 says, "In fact, this is love for God: to keep his commands. " You CAN manage that. It is a thing of the will, with the help of God's grace. The first step is to find out what God commands. There is the two broad principals: Love God and Love your neighbor as yourself. And then their are the applications of those principals in specifics: Don't murder, don't steal, don't gossip, don't fornicate, don't cheat...etc. You find out these commands by reading the Bible. They are in the New Testament, and it doesn't hurt to study the 5 books of law, although there are a lot of Temple laws that no longer apply. Obeying isn't just a matter of "Thou shalt not." There are things we should be doing as well, acts of kindness. We learn to see Christ in the face of the poor, the abused child, the homeless, the single mother, the struggling immigrant. "In as much as you do to the least of these my brethren, you do so unto me." That's how you love Jesus.
Support your study with prayer, or your faith will be dryer than dirt, and a chore. You want a relationship with God, and you can't have a relationship without communication. God cares about you. Share your troubles with him and your joys. Tell him about your day. Give him thanks for all the little things you normally take for granted. Ask him what areas of your life are areas of concern -- places where you are not being the best person you can be, and then listen for his answer. And then together with him, plan what you can do about it. Ask for the grace to proceed. Examine your conscience and see if there are any sins you need to confess to him. And don't forget to pray for the needs of others. It doesn't hurt to end by saying the Our Father. This is how you nurture an intimate relationship.
