This is a very sensible question and also from the heart. As I mentioned earlier, Heaven is where God is. The point to introspect would be: “Do I love Jesus?” If we love Jesus, we would desire heaven. If we are idolatrous – adoring people, talents, intelligence and social connections more than God, we might be lovers of others or ourselves. And so, if someone does not love God, why do they even want to go to heaven? Strange, wouldn’t you think?
Let me be honest here – loving God may not come naturally to us – because we are inherently sinful and lovers of ourselves. But, when Christ comes into your heart and mine, He changes us from the inside – He even changes our dreams and longings and helps us value that which is far better and nobler and more beautiful – than the vain distractions of this world.
So, if you love God, you are on your way to heaven. If you don’t love God, you are the one who is distancing yourself from Him.
C.S. Lewis put it this way: At the end of time, there will be only two kinds of people – one group who say to God, ‘Thy Will be done’ and another group to whom God will say, ‘Alright, thy will be done’.
