Jesus healed the sick, gave sight to the blind, healed those who couldn't talk, made the lame walk, and made the dead rise. Those miracles don't happen today.
Faith isn't blind. It's an assurance of what we already know. That God exists. That Jesus died for us because we repented of our sins and accepted what Jesus did on the cross as payment for our sins. We know that all things work together for good for those of us who love God.
