As Christians, what we do needs to be grounded in what Jesus graciously has done, is doing and will do for us. Otherwise, it will become a joyless, hopeless burden on us. It’s not just “be strong,” it’s “be strong in the Lord.” It’s not just “rejoice,” it’s “rejoice in the Lord.” It’s not just “hope,” it’s “hope in the Lord.” It’s not just “boast,” it’s “boast in the Lord.” It’s not just “have faith,” it’s “have faith in the Lord.” It’s not just “stand fast,” it’s “stand fast in the Lord.” Self-confidence and self-effort will sooner or later lead to self-despair and self-destruction. Remember: It’s not about trying really hard; it’s about relying on the Lord.
