The author of Hebrews exhorts us to hold onto our firm trust, our boldness, our certainty about Jesus Christ because this confidence provides us “a great reward.” We need our faith to tolerate moments of introspection or doubt so that we are able to do “the will of God that [we] may receive what is promised.”
“Therefore, brothers, since we have confidence to enter the holy places by the blood of Jesus, by the new and living way that He opened for us through the curtain, that is, through His flesh, and since we have a great priest over the house of God, let us draw near with a true heart in full assurance of faith, with our hearts sprinkled clean from an evil conscience and our bodies washed with pure water. Let us hold fast to the confession of our hope without wavering, for He who promised is faithful.” (Hebrews 10: 19 – 23)
Our confidence is due to “the blood of Jesus.” Through Christ’s torn flesh, we are able to enter into God’s most holy places and draw close to Him “in full assurance of faith.” Our consciences are clean and so are our bodies. So, we should “hold fast” to our hope. We must realize that God is faithful and never lies. What He promises, He accomplishes.
