"Our business...is to watch our heart-fires. When the temperature of our love lowers, there is cause for terror. It is instructive to mark the many and insidious influences by which the gush and swell of affection are modified." (Biblical Illustrator) There are two things that will cause a decline of love in your heart for JESUS. They are Absorptions and Influences - allowing many things to absorb your time and wrong things to influence you. Never forget - declension begins in the heart. Therefore, keep it "white-hot" for JESUS!
