What does the Bible say about preserving faith?

The Bible teaches that preserving faith is essential for Christians, as illustrated in Hebrews 12:1-2. Here, the apostle urges believers to lay aside every weight and sin that hinders them, emphasizing that we are surrounded by a great cloud of witnesses who exemplified faith and endurance. Faith, in this context, refers to the spiritual faith given by God through Jesus Christ, contrasting with the temporal, unreliable faith found in the world. This spiritual faith is the foundation of our hope and empowers us to persist in our Christian walk amid life's challenges.
