The Bible doesn't explicitly say "don't be concerned if you understand everything." In fact, the Bible encourages seeking wisdom and understanding. However, there are verses and themes that touch on the limits of human understanding, the importance of humility in the face of divine knowledge, and the dangers of pride in thinking you know it all.
Here are a few related concepts and verses:
* The limits of human understanding: Job 11:7-8: "Can you fathom the mysteries of God? Can you probe the limits of the Almighty? They are higher than the heavens - what can you do? They are deeper than the depths of the grave - what can you know?"
* The danger of pride: Proverbs 3:7: "Do not be wise in your own eyes; fear the Lord and shun evil." 1 Corinthians 8:2: "The one who thinks he knows something does not yet know as he ought to know."
* Trusting God even when you don't understand: Proverbs 3:5-6: "Trust in the Lord with all your heart and lean not on your own understanding; in all your ways submit to him, and he will make your paths straight."
* Focusing on obedience and love: Jesus often emphasized loving God and loving your neighbor, rather than intellectual understanding.
* The mystery of God's plans: Isaiah 55:8-9: "For my thoughts are not your thoughts, neither are your ways my ways, declares the Lord. As the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts."
In summary, while the Bible doesn't say it's okay to understand everything, it highlights the importance of humility, recognizing our limitations, and trusting in God's wisdom even when things don't make sense to us. The Bible implies it is impossible for humans to completely understand God's plan and nature.
