There’s a popular verse that says faith the size of a mustard seed can move mountains (Matthew 17:20). So what happens when someone prays in faith—believing with all their heart for a miracle—only to find that their mountain doesn’t move? What do we say to the person who truly believes for healing, only to lose a loved one to cancer, or to watch their own health fail? When the Bible says “the prayer of a righteous person avails much” (James 5:16), how do we reconcile that with unanswered prayer?

For many Christians, these are heart-wrenching moments of crisis. Faith feels like it’s failed, but the reality is far more complex. Prayer, faith, and God’s purposes are not transactional but relational. And just because a specific answer doesn’t come doesn’t mean faith is irrelevant—it just means God’s plan is greater.

Jesus Himself dealt with this tension. In the Garden of Gethsemane, He prayed for the cup of suffering to be taken from Him (Matthew 26:39), but He also prayed for the Father’s will to be done above all. This shows us that faith is not about manipulating outcomes to fit our desires, but about trusting God’s greater will, even when it contradicts our hopes.

The crux of the issue is understanding that faith isn’t a guarantee for our specific desires but trust in God’s perfect plan. A Molinist perspective sees God’s sovereignty and human free will in harmony. God, in His infinite wisdom, knows all possible outcomes. He sees not just our immediate suffering but the eternal good that He is working through it. When we pray in faith, we are invited to participate in God’s will—not to command it.

Jesus performed countless miracles during His earthly ministry, but even He did not heal everyone or remove every obstacle His followers faced. The Apostle Paul pleaded three times for God to remove a thorn in his flesh, and God’s answer was “My grace is sufficient for you, for My power is made perfect in weakness” (2 Corinthians 12:9). Faith isn’t about always getting what we ask for—it’s about receiving God’s grace in all situations, trusting that His will is good.

So what do we say to the person whose prayer seems unanswered? We remind them that God’s will is ultimately for our eternal good, and that His plans reach far beyond what we can see or understand. The promise of the Gospel is not a comfortable, pain-free life, but the hope of eternal glory (Romans 8:18). In the meantime, God often uses suffering to deepen our faith, grow our character, and reveal His strength in our weakness.

Does faith play a determinative role in prayer? Yes, but only in concert with God’s will. Even the smallest faith is effective, not because of the size of our faith, but because of the size of our God. The mountains in our lives may not always move the way we expect, but the God who made the mountains is always with us.

Faith, ultimately, is trust—trust that God is good, even when the outcome is not what we hoped for. And in the end, for the Christian, death itself is not defeat but the final victory. Physical healing may not always come, but ultimate healing—eternal life with God—awaits all who trust in Him. Faith isn’t just for this life; it’s for the life to come.
