By Pastor Chad Fisher, sharing biblical insights to inspire and strengthen your faith and relationship with God.
Faith is one of the most powerful forces in the Christian life. It is the connection point between you and the unlimited power of God.
Jesus said in Matthew 17:20: “For truly, I say to you, if you have faith like a grain of mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move, and nothing will be impossible for you.” (ESV)
The mustard seed is one of the smallest seeds in the plant world, yet Jesus used it to illustrate the potential of genuine faith. Even the smallest measure of faith — when placed in the right Person — is greater than the largest amount of the enemy’s power.
Why? Because the strength of faith is not in its size but in its source. God Himself is behind it.

Faith vs. Willpower
Faith the size of a mustard seed will accomplish more than a lifetime of human willpower or determination. Willpower is limited by human ability, but faith draws from the limitless resources of God.
Many people try to overcome spiritual battles in their own strength, but true victory comes when we trust God’s power instead of our own efforts.
Faith as a Shield
Faith is not only for moving mountains — it’s also a defense against the enemy’s attacks. Ephesians 6:16 says: “In all circumstances take up the shield of faith, with which you can extinguish all the flaming darts of the evil one.” (ESV)
The shield of faith protects your heart and mind from lies, doubts, and fears the devil tries to plant. Those “flaming darts” may come as temptation, discouragement, or false accusations. With faith, you can quench them all.
Faith That Faces Opposition
The enemy will always resist God’s plan for your life. Sometimes the size of your battle is an indicator of the size of your calling. As one preacher said: “Faith that is not tested is not authentic.”
The greater the door God opens for you, the greater the opposition you will encounter. But the same faith that saves you is the faith that will carry you through every trial.
Faith Moves the Hand of God
Faith is the channel through which God’s power flows. Throughout the Gospels, we see people receiving miracles because they believed:
The woman with the issue of blood reached out in faith and was healed (Mark 5:34).
The centurion believed Jesus could heal his servant with just a word (Matthew 8:8–10).
Blind Bartimaeus cried out in faith and received his sight (Mark 10:51–52).
Jesus responded to their faith — not their status, education, or strength.
The Unstoppable Force of Faith
Faith is unstoppable because it connects you directly to God, and nothing is impossible for Him (Luke 1:37).
When you face spiritual mountains — impossible-looking problems, stubborn obstacles, or fierce opposition — faith allows you to speak God’s Word over them and see them move.
Growing in Faith
Even mustard seed faith is powerful, but God wants your faith to grow. Romans 10:17 tells us: “So faith comes from hearing, and hearing through the word of Christ.” (ESV)
If you want to strengthen your faith:
Read and meditate on Scripture daily.
Pray and ask God for His perspective on your situation.
Act on what you believe — faith grows when it’s exercised.
Surround yourself with people of faith who will encourage and challenge you.
Final Encouragement
No matter the size of your faith, place it fully in God. Even a small, mustard seed–sized faith is more than enough when it is rooted in His promises.
Let your faith rise, take up the shield of faith, and watch God move the mountains in your life.
