Just as you do not know the path of the wind, or how the bones grow to fullness in the womb of a woman with child; so you do not know the work of God who makes everything.
then I observed all the work of God, that one cannot understand what is happening under the sun. Though a person may toil in seeking, he will not understand it. Even if a wise man claims to know, he is not able to understand it.
We are bound to thank God always for you, brothers, as it is fitting, because your faith is growing abundantly, and the love of every one of you abounds toward each other.
