The apostle used five illustrations to depict the difference between believers and unbelievers:
1) no partnership, no sharing together, between righteousness and lawlessness;
2) no fellowship, no communion, between light and darkness;
3) no concord, no harmony, between Christ and Belial;
4) no part, no portion, held by a believer with an unbeliever;
5) no agreement, no consent, between the temple of God and idols. These illustrations also unveil the fact that the believers are righteousness, light, Christ, and the temple of God, and the unbelievers are lawlessness, darkness, Belial (Satan, the devil), and idols.
