Faith is not a human achievement — it's a response to God's own voice. The Holy Spirit is the one who stirs belief in the heart; faith itself is a gift worked from the inside out, not a feeling you summon by trying harder. When Scripture says faith comes by hearing the Word, it means the Spirit makes that Word alive in you as you receive it.
Charismatic theology has always insisted on this: faith is not passive intellectual agreement. It is active, Spirit-energized trust that expects God to act. The disciples didn't just believe Jesus could heal — they brought people to him. Abraham didn't just agree that God could give him a son — he stopped counting his own age. Faith moves.
At the same time, the size of your faith is never the point. Jesus said a mustard seed is enough to remove mountains. What matters is the object — the one you're trusting. Small faith in a great God is infinitely more powerful than great confidence in yourself.
