From where Proverbs 28:12 ends, this proverb continues and moves to the next stage. It certainly has some limited application to this world and there are kingdoms even in this fallen world which are more righteous than others.
But how greatly they look forward to the coming of Christ’s eternal kingdom. That kingdom will be perfect and God will never allow it to become corrupted, for ‘there shall in no wise enter into it any thing that defileth, neither whatsoever worketh abomination, or maketh a lie: but they which are written in the Lamb's book of life’ (Revelation 21:27). The minds of believers need to look forward to that perfect kingdom which results from the complete victory of Christ over the powers of darkness. Our minds could not be satisfied with anything less than this perfection because the God we worship is holy and true and without any shadow of turning, and this alone is the God we can worship and do worship, and his Son, Jesus Christ. It is that hope and that perfection – though there is so much that we do not understand about what God will do – that gives backbone to our spirits and enables us to continue walking through the darkness of this world. The darkness will not go on forever. Our hope does not have to hold on forever, to a mere theoretical possibility, but it holds on to a certain coming reality, ‘for now is our salvation nearer than when we believed’ (Romans 13:11). This is the way in which the believer gets through this life and bears the discomfort of seeing evil temporarily triumph. He may not have the power to stop it, but God does have that power and will soon use it, and even during the time when evil is allowed to prevail, it does so under the sovereignty of God. This means that while evil appears to be in charge and unfettered, God secretly works to limit it, steer it, turn it to good account, and make it serve his higher purposes.
