What follows are some contradictory and seemingly contradictory statements for you to mull over.
"Reason ought to conquer imagination." Charles Darwin "Imagination is more important than knowledge." Albert Einstein
Personally, I think Einstein wins the day. His imagination was more far-reaching than Darwin's. Faith is kind of like imagination, plus hope, plus love, plus God. Nothing wrong with Reason for its own sake. Just don't subtract God from your reasoning. And of course, you can't have Biology without Cosmology and Physics. It's the natural order of things.
How about this one:
"I don't want the peace that passes understanding, I want the understanding that brings peace" Helen Keller
Okay, I think I see what Ms. Keller's trying to say and I think she's on to something. She's referring to Philippians 4:6-7: "Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God. And the peace of God, which passeth all understanding, shall keep your hearts and minds in Christ Jesus." It's certainly more important that our hearts and minds stay in Jesus than we understand everything that may be troubling us. However, the Bible is full of examples of those who waited on and stayed within God and He showed up not only with a miracle but with the understanding of what was going on in the spiritual realm. So yes, understanding is good, just make sure it's God's: "the Lord give thee understanding in all things." (2 Timothy 2:7). Not yours only: "lean not to your own understanding. (Proverbs 3:5 NKJV, emphasis mine).
Lastly, here's one for you and God to figure out amongst yourselves:
"And Mary said, Behold the handmaid of the Lord; be it unto me according to thy word." (this is Mary speaking to Gabriel at the Annunciation; Luke 1:38)
"Then touched He their eyes, saying, According to your faith be it unto you." (this is Jesus speaking to some blind men prior to healing them; Matthew 9:29)
Contradictory? No. Complementary? Sure. But how?
