As a spiritual principle, our emotions follow our investment. If we're invested in Christ, we'll have romantic emotions for those in Christ, joy around those in Christ, and love when we work for Christ. This is summed up in Christ's teaching that,
"For where your treasure is, there your heart will be also."
Our emotions follow our investment. If we find ourselves loving the things of the flesh, it's a sign that we need to invest more in the things of the Spirit. And when we do that, our love for the things of the Spirit will grow. Where is your treasure, and where is your heart?
"For the entire Law is fulfilled in in this one word: "You shall love your neighbor as yourself."—Gal 5:14
