What does Hebrews 10:24 mean?

Christianity is not a faith which God intended to be lived out alone. Encouraging others and being encouraged by others are both central to the life of an obedient believer. This follows a core theme of this entire book, which is "holding fast" (Hebrews 3:14).

The book of Hebrews is meant to encourage Christians not to give up on their faith. When persecution and fear put pressure on believers, our response should be to "hold fast" to the truth. This is not blind faith—on the contrary, most of the content of this letter is evidence supporting the fact that Jesus Christ is, in fact, God's ultimate plan for our salvation. Our own personal faith is crucial to that endurance, which is why the writer has so often warned readers not to be lazy or careless about their spiritual growth (Hebrews 2:1–4; 6:1–8). At the same time, the influence of others is extremely important to our spiritual maturity (Hebrews 3:13). Instead of reacting to difficult times with fear or doubt, we should embrace a confident faith and look to encourage fellow believers to do the same. This means calling other Christians to not just "believe," but to act out in love and good deeds.
