In the Old Testament, the Hebrew word translated “integrity” means “the condition of being without blemish, completeness, perfection, sincerity, soundness, uprightness, wholeness.”
Integrity in the New Testament means “honesty and adherence to a pattern of good works.”
Adherence - Great devotion or faithfulness to someone or something
“Integrity” in our world today implies moral incorruptibility.
Christians should be those who cannot be bribed or compromised because we serve God rather than men (Colossians 3:17, 23; Acts 5:29).
We are to be people who keep our word (Matthew 5:37; James 5:12).
We are to love those around us in both word and deed (1 John 3:17–18; James 2:17–18; Ephesians 4:29).
We are called upon to believe in God and therefore to follow Him in all our ways (John 6:19; 15:1–17).
Our lives should line up with our belief in God and evince a trust that His ways are best (Proverbs 3:5–6).
