What about the believer that loves the world and says that if being a beggard in heaven is going to be great, then is comfortable with that, and so he lives a life doing the minimum for God?

If I understand the question correctly, you’re asking about a person who is half-hearted for God. And he is unmotivated to be whole-hearted because he figures he’s going to make it to heaven anyway, which is going to be wonderful regardless of how much he loves Christ here in this life, even though there will be little to no reward waiting for him.  

So if I got the gist of the question, this is not an uncommon one. And to me, this question is a “cousin” to the question the Apostle Paul addressed in Romans 6:1, “Are we to continue in sin so that grace may abound.” In the chapter before this, in Romans 5, Paul completed a glorious description of the grace of God through Christ, grace that gives us a brand new life, grace that is by definition undeserved. So one obvious conclusion that Paul addresses in Rom 6:1 is, “Well, if I’m saved by grace, then I can do whatever I want, including sin.” Paul continues on in vs. 2 by strongly saying, “By no means! How can we who died to sin still live in it?”

The question above is worth a couple of sermons, but let me give just one of several important answers to it. If any of us believers (including me) love the world, this is the first problem. Why do we even think this way?

It’s because, in large part, we simply doesn’t understand the gospel. We don’t understand how the wrath of God was stirred up against us, and in spite of our rebellion, the Lord mercifully sent his Son to die in our place and rescue us from eternal destruction. I’ll say it again: we are rescued from eternal destruction! Do we understand the profoundness? So now as believers, if we love something more than the Lord, we are unimaginably ungrateful, self-centered, disloyal, and rebellious people. It’s like having someone rescue you from drowning, but you simply don’t appreciate it, and you barely acknowledge what the rescuer did. Your friends would be shocked and appalled by your treatment of the rescuer. They would wonder why you have such a cold heart. Now multiply that scenario times 1000 and we get closer to the situation where we love the world more than we love God.

That’s one very brief answer.

A few other possible responses I could expound on (if I could give a few more sermons!):   :)

  1. We simply don’t fear God. We trivialize and underestimate who he really is: Lord Almighty and Creator.
  2. We are deceived and don’t grasp the destructive power of sin in our lives, for “loving the world” is, plain and simple, sin. And sin is always destructive and never does us any favors (Romans 6:21).  
  3. We don’t understand that our half-heartedness will lead to little or no rewards in heaven, and this should grieve us. See 1 Corinthians 3:10-15.
  4. If our heart is this cold towards the Lord, a real possibility is that we have never truly repented of sin and believed in the Lord Jesus, and we have never had the Holy Spirit dwelling within us. “If anyone loves the world, the love of the Father does not live in him” (1 John 2:15). And Jesus said plainly, “Bear fruit in keeping with repentance.” Fruit does not save us, but it is the mark of salvation. If this is where we are, then we should quickly get before God, humble ourselves, repent, and believe in the Son. Then walk with him in a life of fruitfulness, and so be assured that Christ indeed does dwell in us.
