God is love without passions

The expression: "God is love without passion" of Thomas Aquinas has a similarity with the biblical passage: "There is no fear in love. But perfect love drives out fear, because fear has to do with punishment" 1 John 4:18.
Talk about punishment is talk about sin, is to talk about to go against the law.
We cannot attribute passions to God because passions have their own will. A will for reason and a will for passion, God is not divisible.
Tomas Aquinas explains that the expression, the wrath of god in the old testament is a meta metaphor.
We can only attribute perfections to God, this perfections are called gifts.
