1 Everything has its own time—a time for all that happens here:3:1. This is the Teachers observation, not his instruction. For this reason the verb participle is used, rather than the infinitive, since the infinitive might suggest that this is what should happen, e.g. "a time of killing" (i.e. when it happens) rather than "a time to kill" (when it ought to happen).
11 Everything God does is beautifully timed, and even though he has also placed the idea of eternity3:11. "Eternity": the word used here has the meaning of ages past and ages future, "continuation to the most distant time." in our minds, we can’t fully understand what God does from beginning to end.
14 I also concluded that everything God does lasts forever: nothing can be added to it or taken away from it. God acts in this way so that people may stand in awe of him.
