'Changed' in the Bible

So then, was I indecisive or capricious when I was [originally] planning this? Or the things I plan, do I plan in a self-serving way like a worldly man, ready to say, “Yes, yes” and “No, no” [at the same time]?

But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord.
