Perseverance must finish its work so that you may be mature and complete, not lacking anything. . .
Blessed is the man who perseveres under trial, because when he has stood the test, he will receive the crown of life that God has promised to those who love him.
James 1: 4 and 12
It's not about pretending everything is fine, it's not about never having disappointments or failures.
It's about clinging to God despite all that. It's about who we have relied on through the whole journey, not just when we felt like it.
That is what real faith is about; that is a faith that lasts, endures for ever.
