But exhort one another every day, as long as it is called “today,” that none of you may be hardened by the deceitfulness of sin. (Hebrews 3:13 ESV)
Exhortations are strong advisements meant to keep believers from straying sway from God by pointing them upward to his statutes and decrees. When we exhort fellow saints, we are trying to help them preserve their hearts. How we do it matters because we never want to speak in a condemning or hurtful manner. If anything, we should always premise an exhortation with love and concern for their well-being. Our sinful natures have a tendency to rebel if we feel that our exhorter is being a bossy, self-righteous, know-it-all. Speaking the truth in love and keeping Jesus as the root of an exhortation is always the best approach (Ephesians 4:15).
“Above all, keep loving one another earnestly, since love covers a multitude of sins” (1 Peter 4:8).
“Let him know that whoever brings back a sinner from his wandering will save his soul from death and will cover a multitude of sins” (James 5:20).
