Used as an adjective, the word whole comes from the Greek words of holos and holokleros meaning all, entire and complete. These two words come from the noun holokleria meaning completeness.
In the biblical context of health and wellness, wholeness might mean being well in spirit, mind and body. In Paul’s letter of encouragement to the Christians living in Thessalonica, he addresses an aspect of their wholeness when he prays for them:
“Now may the God of peace make you holy in every way, and may your whole spirit and soul and body be kept blameless until our Lord Jesus Christ comes again. God will make this happen, for he who calls you is faithful.” 1 Thessalonians 5:23-24
