For you have need of endurance, so that when you have done the will of God you may receive what is promised.
There is a life pattern here that the author of Hebrews encourages his readers to remember and keep in practice. He has spoken to them about the way in which the trials of persecution have marked them. They persevered despite the pain (Hebrews 10:32-34). Confidence in trial has been a subtheme throughout the book as well (see Hebrews 3:6; 4:16; 10:19).
The encouragement will continue through the rest of the book where endurance is commended (Hebrews 12:1), stability in the life of obeying God's will is encouraged (Hebrews 13:21), and the future hope of a promised eternal salvation is lifted up as a goal (Hebrews 4:1; 6:12; 8:6; 9:15).
And this is my confidence: I must endure hardship, perhaps persecution, faithful to the will of God as He reveals it in His Word, looking to future hope when my salvation is complete with Christ in glory.
