Christians cannot expediently separate the purity of the soul from the purity of the body.  Holiness involves being set apart in the total person, including spirit, soul and body.  In a culture where sex is honored as the highest of pleasures, Christians must be vigilant in sexual purity if they would inherit the Kingdom (I Co 6:9).  When the body is given to God as a living sacrifice, it becomes our “spiritual service of worship” (Rom 12:1-2).

“For this is the will of God, your sanctification; that is, that you abstain from sexual immorality…For God has not called us for the purpose of impurity, but in sanctification.” 1 Thessalonians 4:3, 7 (NASB)
