Whenever God begins something, we have the assurance that He will finish it. Nothing will stand in the way of Him accomplishing His purpose in this world and in our lives. What God starts, He finishes, and nobody can hinder Him. Sure, delays will happen. Just remember, God is in charge of the delays as well as the progress.
There will come a time when everybody will know why, for what purpose, there is all this suffering, and there will be no more mysteries. But now we must live ... we must work, just work!
We scientists, whose tragic destination has been to help in making the methods of annihilation more gruesome and more effective, must consider it our solemn and transcendent duty to do all in our power in preventing these weapons from being used for the brutal purpose for which they were invented.
Find the thing you want to do most intensely, make sure that’s it, and do it with all your might. If you live, well and good. If you die, well and good. Your purpose is done
