The preachers who have distorted the Gospel, by not teaching what Jesus and the NT writers said about suffering and the condition of this world have much to answer for. I grew up with some misconceptions but was often made to recognize from the words of Jesus Himself that things will not always go the way I want them. We learn how to overcome our doubts in these situations by the Holy Spirit working in us and opening our hearts and minds to His life-giving words in the scripture.
