Daniel 5:22a
"O Belshazzar, you have not humbled your heart, though you knew all of this.”
Now Belshazzar was well aware of the things that happened to his grandfather, king Nebuchadnezzar. The madness that he experienced until the seven seasons had passed over him, his restoration, the proclamation that his grandfather made, "there is no god in all the earth like the God of Daniel who is able to set up those whom He would and bring down those whom He would. And sets in authority those whom He will." (Daniel 5:21) Belshazzar knew all of this yet; he blasphemed the God in whose hand his very breath was in. (Daniel 5:23)
There will always be people like Belshazzar who will belittle the existence of God. People who seem to be so forward in their mockery, ridicule, and blasphemy of God, that they have no fear of Him within their hearts at all - just brazenly living in open denial.
Are these people beyond His reach? - Absolutely not. Will the Lord continue to make His presence known to those who constantly deny Him? Sadly no. Therefore, humble yourself before God while you still have time, ask His forgiveness and be cleansed.
The Truth
“Therefore whoever confesses Me before men, him I will also confess before My Father who is in heaven. But whoever denies Me before men, him I will also deny before My Father who is in heaven.” (Matthew 10:32,33)
