Hebrews 10:35-38
"Do not let this happy trust in the Lord die away, no matter what happens. Remember your reward! You need to keep on patiently doing God's will if you want Him to do for you all that He has promised. His coming will not be delayed much longer. And those whose faith has made them good in God's sight must live by faith, trusting Him in everything. Otherwise, if they shrink back, God will have no pleasure in them."
