Terry, there is no promise that he will not give you more than you can handle nor that he will allow you to have more than you can handle. ( 1 Corinthians 10:13 is the miss read verse leading to this teaching)
ask yourself this. if he wont give us more then we can handle and we can handle anything that comes our way, then why do we need God at all?
Truth is his promises are all spiritual (on an eternal level) and not ephemeral. We may indeed be given something here on this earth, this life, that we cannot handle but, we can rest in his word, that if we trust in him, Christ, we will have the ultimate victory in the end.
Preaching over.... Have a blessed day!
