Hebrews 3:6 (NLT2)
6 But Christ, as the Son, is in charge of God’s entire house. And we are God’s house, if we keep our courage and remain confident in our hope in Christ.
Because God lives in us believers, we can remain courageous and hopeful to the end. We are not saved by being steadfast or firm in our faith, but our courage and hope does reveal that our faith is real. Without this enduring faithfulness, we could easily be swept away by the winds of temptation, false teaching or persecution.
