So when God desired to show more convincingly to the heirs of the promise the unchangeable character of his purpose, he guaranteed it with an oath, so that by two unchangeable things, in which it is impossible for God to lie, we who have fled for refuge might have strong encouragement to hold fast to the hope set before us. We have this as a sure and steadfast anchor of the soul (Hebrews 6:17-19).
Sir Francis Bacon famously said that “knowledge is power.” The author of the book of Hebrews would agree. For Christians, our knowledge of God, his unchangeable nature, his works in history and his promises for the future is powerful. This knowledge strengthens our faith. It provides a sure and steadfast anchor for our souls and the hope that we have. Hope of our future glorification. Hope that Jesus will come again. Hope for the new heaven and the new earth.
When the winds of doubt assail our assurance of salvation, we can hold fast. When the waves of uncertainty threaten to drag us away from our faith in Jesus alone, we can hold fast. We have a sure and steadfast anchor for our souls.
