Amen, I preached a sermon similar in January, 2011 and as I preached it to the congregation, there were areas in my life that were changed.

“Immediately the boy’s father exclaimed, ‘I do believe; help me overcome my unbelief.’”
Mark 9:24 NIV
“No sooner were the words out of his mouth than the father cried, ‘Then I believe. Help me with my doubts.’” Mark 9:24 MSG

The theme of faith saturated Jesus’ entire ministry (examples: Matthew 9:22; Matthew 15:28; Mark 2:5; Mark 10:52). Thus, the prerequisite to becoming a Christian is faith, “for without faith it is impossible to please God.” Ultimately, the Christian’s walk is a faith walk encumbered with many turns and curves. For often as we travel the faith path, we will encounter detours, speed bumps, curves, and even some mishaps. These detours will often play upon one’s faith, one’s belief system in God’s presence and power. But the Apostle Paul declared just because man doesn’t believe it doesn’t mean that God cannot be trusted (Romans 3:3). People trust in many things and some even trust in God. However, one’s level of trust is expounded based on one’s walk with God. See, Christians believe that Jesus is the Son of God. They even believe the stories in the bible about Christ’s miracles. They believe Christ was born of a virgin, endured affliction and brutality, crucified on the cross, resurrected from the grave, and ascended to His Father. But they can’t believe that Christ will resurrect their dreams, heal their diseases, open their eyes, and put a pep in their steps. See faith is never perfect; belief and unbelief are often mixed. God tries our faith that we may try His faithfulness. There are moments in our lives that our faith is so weak because of the pressures we face.
• You tried one doctor after another
• You tried radiation
• You tried chemotherapy
• You tried medication
• You tried surgery
• You tried changing diet
• You tried curtailing spending
• You tried the marriage counselor
• You tried the laying of hands
• You tried honesty but the dishonest prosper
• You tried being compassionate towards others only to be mistreated by them
• You tried, you tried, you tried. Yet, nothing change. The situation remained the same.
So the question is “How do we overcome unbelief when life isn’t fair and how do we trust a God who sees imperfections but doesn’t stop them?”
I’m glad you asked. Church, I’m here this morning to tell you that uncertainty and doubt about God’s promises and presence are part of life. Because we are human beings, it is quite natural for us to struggle, to doubt, to question, to wonder about God’s presence and promises at various times. Therefore, we find it difficult to maintain our faith in who is to be a “Perfect God” when imperfections crush and overwhelm us. However Church, we must still have faith in a perfect God when imperfection is all around us? We need to emulate the example of this father who whispered a prayer to God, “Lord, I believe but help me overcome my unbelief.” We are to put aside, cast down imaginations and strongholds, that is, all of our thoughts, ideas, and beliefs that are contrary to the Word of God.
