Now faith is the substance of things hoped for, the evidence of things not seen. For by it the elders obtained a good report.
One of the most frustrating things for unbelievers is the faithful calm of the devoted Christian. Jesus Christ frustrated the Pharisees and Saducees with patience and firm determination in the Truth. These characteristics can help us too. Our hope rests in faith. Faith gives us the hope we need to be patient when others grow angry. Faith lends us that same Christ-like determination to do the will of the Father.
When all else fails, trust the faith handed down by Jesus Christ to the Apostles. It is the stuff of hope.
