Salvation comes, not from your faith, but from God’s faith. It is belief that through God, all things are possible, and the mountains in your life can be moved.
“And when He had come into the house, the blind men came to Him. And Jesus said to them, “Do you believe that I am able to do this?” They said to Him, “Yes, Lord.” Then He touched their eyes, saying, “According to your faith let it be to you.” And their eyes were opened. And Jesus sternly warned them, saying, “See that no one knows it.”
Matthew 9: 28-30
