Boldness in Faith, Living in Grace, Holding to Eternity
In the first 11 chapters of the Book of Hebrews, the author gives us unassailable reasons for trusting in God regardless of current or long-term situations.
He continues in chapter 12 to exhort us to walk boldly in our faith knowing all that God has done and given us. Hang tightly to that which is from God since everything else is destined for destruction.
