It is proper Christian thinking to talk about our unworthiness and general horribleness. Our heads puff as we utter, “I am not worthy of heaven.”
Certainly there is truth in these utterances and it may indeed be possible I’m being cynical a tad. But I do think we often go overboard in our voluntary humility to the extent we miss biblical teaching.
You can indeed be worthy of heaven. And, for our NIV readers, “worthy” means “to deem entirely deserving.” Yup, it is possible to claim that you deserve heaven.
Now, don’t go saying that because I said so, listen to Jesus talk about a group of people who “shall be accounted worthy to obtain that world, and the resurrection from the dead.” “Accounted worthy” means deserving.
Or perhaps you’re a Paul guy. Well here’s Paul talking about the suffering Thessalonian believers that they “may be counted worthy of the kingdom of God.” “Counted worthy” is the same Greek word and it means to deserve.
It is possible to deserve heaven, now I suggest you figure out how to go about deserving it!
