The Bible never defines God as anger, power or judgement--in fact it never defines him as anything other than love.
Chalke and Mann, the lost message of jesus, p. 63
It really didn't take much thought to see that there is something bad wrong with that statement.

And this is only a small sampling of the verses I found in word searches for "holy", "anger", "wrath", and "judgment".
Chalke seems to want to take the one statement from I John, "God is love", and make it the focal point of the whole Bible. Considering all of the other things the Bible says about Him, particularly the thrice-repetitions "Holy, holy, holy", we must needs take care of taking that one statement, true as it is, and setting it up as being the thing by which God defines Himself. A far stronger case could be made for God's holiness being the thing by which God most strongly defines Himself.
But that may be scary to some people (no surprise). Some would rather have a "grandpa in the sky" who makes rules than winks when you break them, than a God who says what He means and means what He says.
And this is one thing we must avoid. It is quite proper to speak of God's love, but not at the expense of all else the Bible says about Him, and it certainly raises questions when one phrase in one book is taken from its context and made the lens through which one sees the rest of the Bible.
