Confidence in our sanctification

Passage: 1 Thess 28:5-23-24 Description: The Christian life is a race run on rocky ground. Yes, we stumble. We trip over the same roots that caught us last month. We run with a limp, and some days we crawl on this crushing narrow road. If finishing this race depended on the steadiness of our own feet, not one of us would cross the line. But God is immovable and never stumbles. He never trips, never tires, never loses His grip, never walks away from a work He's begun. We can fully rely on His shatterproof ability and tireless faithfulness to work out our soul-cleansing sanctification.
