How do we know faith is real?

The authenticity of faith is often revealed through affliction. As discussed in 1 Peter 1:6-7, 'The trial of your faith, being much more precious than gold, that perisheth,' illustrates that just as gold is tested by fire, so too is true faith tested through hardships. When believers face trials, it proves the integrity of their faith; if their faith endures under pressure, it demonstrates that their relationship with Christ is genuine and steadfast. Those who truly believe will find that their faith grows stronger as they navigate through life's afflictions.
