As Paul opens his second letter to Timothy, he writes not just as an apostle, but as a spiritual father to his beloved child in the faith. In what may seem like a typical greeting, Paul reveals the foundation for Christian endurance: the promise of life in Christ Jesus. This hope is not abstract—it’s what sustained Paul through suffering, and it’s what he urges Timothy to cling to as well. Endurance is possible, not through strength of will, but through the unshakable promise of life found in Christ.
