To be a scientist you have to be willing to live with uncertainty for a long time. Research scientists begin with a question and they take a decade or two to find an answer. Then the answer they get may not even answer the question they thought it would. You have to have a supple enough mind to be open to the possibility that the answer sometimes precedes the question itself.
If you love Christ, never be ashamed to let others see it and know it. Speak for Him. Witness for Him. Live for Him.
