Unlike changing a flat tire, just one experience rarely fixes a spiritual problem. It takes time, conversations, and encouraging experiences that will help rebuild faith. It comes more like the dew from heaven than a one-time blast from a firehose. You have to minister again and again as you help someone turn back to God and again rely on the Savior and His Atonement.
How we live our lives increases or diminishes our faith. Prayer, obedience, honesty, purity of thought and deed, and unselfishness increases faith. Without these, faith diminishes. Why did the Savior say to Peter, “I have prayed for thee, that thy faith fail not”? Because there is an adversary who delights in destroying our faith! Be relentless in protecting your faith.”
