Dre, I think there’s still a bit of confusion. Heaven is a central belief in Christianity, but loving God isn’t about going to heaven; loving God is about loving God. The reward for loving God is God.
Again, the Jews in the OT did not know about heaven. There was none of this quaint (and heretical, imo) talk of “asking Jesus into your heart” and receiving some kind of “once saved, always saved” eternal life package and being set for a comfy eternity. The practicing Jews knew that in their lifetimes, it was God’s way or the highway, and it was their joy to follow him. Btw there is more in the OT about God’s love, kindness, and mercy than there is about his anger or wrath, as there should be.
In the NT, Jesus talked about heaven some and revealed it in part to the apostle John in the book of Revelation, and thus the Western world is highly aware of this Christian concept called heaven, although I think most people don’t have a sound understanding of it at all. Yes, this has led to people choosing to label themselves as Christians because they want to go to heaven, but not actually living like a Christian… And I don’t think that such people will in fact go to heaven, because it’s likely that they haven’t accepted God’s gift of forgiveness, repented, and decided to follow him. But honestly, I don’t know anyone who is serious about their faith whose motivation is skewed to the point that they love God just because they want to go to heaven or want eternal happiness. When you actually love God, he gets you hooked and draws you in; and yes you want to go to heaven (a lot), but only because God is there and you have the option of being with him forever and enjoying him with lots of other people who want to be with him too.
When God revealed consequences of loving him or not loving him, he knew what he was doing. You say that the consequences take the place of God’s love as one’s motivation for being moral and loving God. I would say that if that’s true, then God’s love was never actually received or reciprocated in the first place, and there was never much of a Christian faith… and even so, God can still use the inferior motivation as a springboard into the superior one. The revelation of the concept of heaven didn’t create a new breed of people who don’t love God—such people have always existed. (Also, I believe that if you’re earnestly trying to love God then over time he helps you love him.) When Jesus and the apostle Paul talked about heaven, they were encouraging people who already believed in God. Heaven is encouraging to believers—again, not because it’s heaven, but because God is there and corruption isn’t. It provides hope.
There’s an element of reality for a Christian or Jew that the Bible calls the fear of the Lord, which is a healthy and invaluable element, and it’s hard for most to understand. It’s not like the gripping, debilitating fear that a little boy feels upon breaking a window as he awaits the return of his tyrannical father from work. It’s the stirringly painful awareness of how wicked and tiny I am compared to God, and how holy and big he is. This is what leads some people to seeing their need for him, to repentance, and ultimately into God’s love. It’s what’s keeping me from looking at porn right now, even though it’s late at night and I’m on my laptop and there’s no one around me. I know that God is watching me, and I have deep respect for him. “The fear of the Lord” and love for him are inseparably connected. If fear is your primary/only motivation for morality and hope, then you probably view God as a heartless tyrant, in which case you need a lot of love to understand who God really is. If attraction- and feelings-based love is your only motivation, then you probably view God as an over-colloquial pal who has a delightful smile no matter how much you sin, in which case you need a healthy dose of the fear of the Lord to understand who God really is.
Which brings me to your quote: “Not to be a smartass, but considering what the OT God did to people who didn't love him I'd choose to love him too.” Maybe, maybe not. Would you? Honestly think about it. I hope you would, my friend.
Regarding sex and Christianity: Well, firstly Dre I don’t understand how the need for food can be an accurate analogy for the desire for sex, but I want to understand, so until I see where you’re coming from I won’t respond to that specifically. Also, I’m sure sexual frustration is torturous for some, but I don’t believe I’ve ever experienced it. And I’m your textbook definition of abstinence before marriage. My body seems totally fine with it. If your body will automatically ejaculate periodically if you don’t stimulate it yourself (a point you brought up), then why is it that bad to not masturbate or have sex?
I care a lot about people understanding the Christian worldview; it's so poorly represented today. So I hope this helps. But FYI, I’m going to a wedding this weekend so I won’t be back on for a few days.
