Lysa TerKeurst in her book What Happens When Women Say Yes to God wrote this:
"A real sign of spiritual maturity is looking to God not for comfort and convenience but for purpose and perceptive. Comfort and convenience lead to complacency. When trouble comes, the complacent person becomes critical of everyone, including God. On the other hand, purpose and perspective lead to the perseverance that is evident in those living a truly devoted life. The persistent person eagerly looks to handle trials and struggles in a way that honors God and allows personal growth."
