Consider: When the Son of Man comes, will He find the faith on the earth? (Luke 18:8)
"The faith of Paul and the other apostles was a revolutionizing thing. It upset the whole life of the individual and made him into another person altogether. It laid hold on the life and brought it under obedience to Christ. It took up its cross and followed along after Jesus with no intention of going back. It said goodbye to its old friends as certainly as Elijah when he stepped into the fiery chariot and went away in the whirlwind. It had a finality about it. It snapped shut on a man's heart like a trap; it captured the man and made him from that moment forward a servant of the Lord. It turned earth into a desert and drew heaven within sight of the believing soul. It realigned all life's actions and brought them into accord with the will of God. It set its possessor on a pinnacle of truth from which spiritual vantage point he viewed everything that came into his field of experience. It made him little and God big and Christ unspeakably dear...
The faith will command or it will have nothing to do with a man. It will not yield to experimentation. Its power cannot reach any man who is secretly keeping an escape route open in case things get too tough for him. The only man who can be sure he has true Bible faith is the one who has put himself in a position where he cannot go back. His faith has resulted in an everlasting and irrevocable committal."
"For yet in a very little while, He Who is coming will come, and will not delay. But my righteous one shall live by faith; and if he shrinks back My soul has no pleasure in him."
Hebrews 10:37, 38
"And now little children, abide in Him, so that when He appears, we may have confidence and not shrink away from Him in shame at His coming."
1 John 2:28
