You should, and it’s biblical. That it, if you believe verses like Prov. 13:24, which says: “Whoever spares the rod hates his son, but he who loves him is diligent to discipline him.” And, if Jesus believed the Bible, then I think we can to.
Still squeamish about? Then maybe you should check out this post by John Piper, pastor at Bethlehem Baptist Church.
Because we are small-minded, big-headed and have a too-small view of God, there is an idea that people sometimes hold that heaven will be boring. Think about it, that feeling that you’ve been there, seen it all and now are looking for the next big thing. Only, the problem is that there is no next thing because heaven is it. Somehow, there are people who are willing to risk an eternity in hell because they believe that heaven will somehow be unsatisfying.
After all, doesn’t Paul say in I Corinthians 13:12: “Now I know in part; then I shall know fully, even as I have been fully known”? Yes, but we shouldn’t assume that just because we will be made perfect we will know everything there is about God. John Piper, as part of an article at the Desiring God blog, gives an explanation, based on other passages:
What Paul means [in I Cor. 13:12] is not that I will know exhaustively the way God knows me, but rather I will know accurately the way God knows me. The point is not that I won’t have limits to what I know, but rather I won’t have mistakes in what I know.
God is infinite and therefore inexhaustible in the complexity of his glory. His created universe, as the Hubble telescope shows, is big. His thoughts toward us are countless. And his ways are beyond finding out.
Part of what makes “eternal life” satisfying (and not boring) forever is that it will take an eternity for perfect, finite creatures like us to know God fully. He is perfect and infinite. We will be perfect and finite. He will enjoy increasing revelation of himself, and we will enjoy increasing jubilation in him—forever.
So, this idea that eternity in heaven can’t match up to a lifetime of sin and an eternity of punishment in hell doesn’t cut it.
