Complete trust in God, using whatever human means are necessary in each situation, gives an incomparable fortitude and a special kind of serenity to the Christian, whatever may happen to him and whatever the tribulations he may have to face up to.So there are two things to think about here, for me anyway.
Francis Fernandez, In Conversation With God, vol. 4
First, how complete is my trust in God? Do I have that special kind of serenity?
Second, am I using whatever human means are necessary in each situation? I know people who will say they have complete trust in God and then laze around waiting for whatever they've been praying for to drop into their lap.
It takes a fine balance to encompass these two things well.
