Proverbs 26:12 Do you see a man wise in his own eyes? There is more hope for a fool than for him.
If we are going to try measure our own goodness or self-worth through our own knowledge then we will either come to the conclusion we are the best thing in the world or we are a total failure.
If we try to set our own examinations we will either set questions we already know the answer for or set impossible questions; it just does not make sense!
We need an external measurement or comparison which normally means listening to someone else’s judgement of us.
God has given us the Bible as our measuring stick but also given us the Bible as our solution finder when we see we have failed. Trust God’s Word.
