My King James' version gives the translation of this verse as " O Lord I know that the way of man is not in himself ; it is not in man that walketh to direct his steps"
My " Good News Bible" gives it as " Lord, I know that noone is master of his own destiny; no person has control over his own life".
( Sorry, this is not one of the Hebrew books of the Bible on my bookshelves, so can't get at it with my hebrew dictionary)
Both of these are a bit clearer than goodlife's version, but they both seem to state the obvious, whether you are religious or not. It says " you can try, but you can't make your life follow the path you want it to."
What it boils down to is:
"stuff happens"
The verses before this one, and the verses after it do not seem to carry a ringing message about god being the great director of people's destinies, as we have come to expect from goodlife
By the way, was there a question in there ?
