Hi!!!
I �m a Spanish speaker and I �ll try to help you...
First thing, I don �t correct your version because for me translation is not always objective, so this is my version:
"GOD GAVE MAN WISDOM SO AS TO USE HIS OWN CREATION PROPERLY. LET �S UNDERTAKE THE TASK OF FORMING FUTURE GENERATIONS TO PRESERVE GOD �S GIFT".
I used GIFT not to repeat CREATION again, at the end, God �s creation is a gift...
Anyway, I hope it can help you...
I don �t know if it is perfect but it is what I would say or translate into English.
Bye and have a nice Sunday!
Cori =)
