Israel
The sin of Achan and its results teach the great truth of the oneness of the people of God, (Joshua 7:11). "Israel hath sinned." See in illustration; (1 Corinthians 5:1-7); (1 Corinthians 12:12-14); (1 Corinthians 12:26). The whole cause of Christ is injured by the sin, neglect, or unspirituality of one believer.
