Awesome and awful can be interchangeable in that regard, as can other words, like terrible
There are high-church prayers that begin, "O great and terrible God..."
see Deut. 3:21--Thou shalt not be affrighted at them; for the Lord thy God is among you, a mighty God and terrible.

Deuteronomy 3:21 NIV: Moses Forbidden to Cross the Jordan
At that time I commanded Joshua: "You have seen with your own eyes all that the LORD your God has done to these two kings. The LORD will do the same to all the kingdoms over there where you are going.
Ezekiel 25:17 (NIV):
I will carry out great vengeance on them and punish them in in my wrath. Then they will know that I am the Lord, when I take vengeance on them.
The word Awesome in the Bible means: amazing, characterized by reverential fear. Throughout the Bible it is used to describe God. I am not saying you shouldn't use the wordawesome I am mereley pointing out that some may argue or take offense to that word being used other than describing God. Think of it like, when people say you should not use the Lords name in vain. Some people are offende when other do that.
My point was that the word awesome being turned into a word that means the total opposite, bad, unpleasant, ugly, some might not agree.
That's all.
