The Bible teaches how to build confidence in God, not self.
Learning why we distance so we can learn how to draw closer to God.
Pray about your lack of trust in God. What areas of your life are you unwilling to trust God with, and how has this affected your desire to pray? How has it affected your desire to read your Bible?
Regret is painful, but when it is attached to spiritual failure (mistakes or sins), it can destroy our faith.
