What does Hebrews 4:16 mean?
The central figure of the Christian faith is not some remote deity, a flawed spirit, or a being with no understanding of human nature. If that were the case, then prayer would be a terrifying and possibly meaningless experience. Fortunately, for the Christian, Jesus not only understands our struggles and failures (Hebrews 2:14–18), He has overcome them first-hand (Hebrews 4:15).This verse is the conclusion of a point begun in verse 14. After encouraging Christians to complete the works God has given us (Hebrews 4:1–11), the writer reminds us that God's word is the ultimate measuring stick for all of our thoughts, deeds, and intentions (Hebrews 4:12). Nothing is hidden or obscure to God, who is our ultimate judge (Hebrews 4:13). Verses 14 and 15 make it clear that we can maintain our faith in the face of struggles, knowing that Christ has already shown us the way. He not only experienced suffering, death, and temptation, but did it without succumbing to sin.
Knowing, then, that Christ fully understands our weaknesses and has experienced our pain, we can pray. When we come to God asking for mercy, grace, help, or forgiveness, we can be confident (Hebrews 3:6) and assured. Nobody understands our pain better than Jesus, which is why only Jesus can be our High Priest as well as the substitute for our payment of sin (Hebrews 2:18).
