Faith does not spring forth from our inmost self, no matter how much spirituality we practice or how many good deeds we do. It comes from outside of us and then lodges itself inside of us. It's not our senses which give us faith, but the Spirit through the Word of God, who then lights up and directs our senses and our reasoning. It's not how strong your faith is, but it's who the faith is in. We do not even have a right faith on our own accord, but through the work of the Holy Spirit.
Faith is caught rather than taught.
It grasps us and redefines who we are. We open up to it in hope because the Spirit works through other people who live their faith honestly and bear its message to those who haven't grasped it yet. It is done and shown in concrete ways of daily living and in 'moments of truth' where matters of faith most clearly make the key difference. Faith trusts God to forgive. Faith trusts God to make holy.
