Sounds like you dont love or admire God for who he is, you just dont want hell. Spend more time with him in the word. Talk to him prayerfully throughout the day. Admire the beauty of his creations. Realize that he loves you unconditionally, but will not tolerate the sin you keep disrespecting him with. We all stumble occasionally, resist the temptations and ask him for help when you know it's a battle you cant win. You feel nothing when you hurt God because you have let your heart turn cold towards him. God can fix this but you have to let him in. Invite the Holy Spirit to live in your temple. Seek out new facts about the Father, the Son, and the Holy Spirit. Get out of the worldly mindsets that assualt us on a daily basis and get out into nature to appreciate his gift to us we often neglect due to TV, facebook, and dead end jobs.
You kindle love by spending time with a person. Spend time with God, be appreciative of what he has given us, the small things and the life changing things he has accomplished in your life. I try to talk to Lord Jesus in appreciation often. It humbles me to think that someone so much greater than I cares so much for me. He deserves my loyalty, respect, and admiration. Jesus is the coolest dude I know.
