The verse ( Ecclesiastes 11:5) confirms that we cannot and do not need to fully understand everything about God or his works. God is sovereign; he is all-powerful and all-knowing. He is not like us; his thoughts and ways are higher than ours. Even though he reveals himself (through creation, scripture, Christ), his fullness remains beyond our understanding (Deuteronomy 29:29). The scripture is not saying that we shouldn't seek to know God; we absolutely should, but the fact is that we cannot know him exhaustively. We do not need to understand why God allows certain things or how exactly he works in every situation to trust that he is sovereign, good, and working out his purposes. This verse frees us from the feeling that we need a complete intellectual understanding of God's nature, actions and ways. We cannot know everything about God or his works. Therefore, we do not need to understand everything about God or his works. We just need to trust him and have faith in him. He doesn't need to prove anything to you.
