1 Thessalonians 5:23-24
23 May God himself, the God of peace, sanctify you through and through. May your whole spirit, soul and body be kept blameless at the coming of our Lord Jesus Christ. 24 The one who calls you is faithful, and he will do it.
Soul = psuche
Any action initiated by the soul = psuchikos
Natural, sensual, worldly, unspiritual, without the spirit, or to follow their natural instinct.
1 Corinthians 2: 14-15
14 The person without the Spirit does not accept the things that come from the Spirit of God but considers them foolishness, and cannot understand them because they are discerned only through the Spirit. 15 The person with the Spirit makes judgments about all things, but such a person is not subject to merely human judgments
Jude 16-19
16 These people are grumblers and fault finders; they follow their own evil desires; they boast about themselves and flatter others for their own advantage. 17 But, dear friends, remember what the apostles of our Lord Jesus Christ foretold. 18 They said to you, “In the last times there will be scoffers who will follow their own ungodly desires.” 19 These are the people who divide you, who follow mere natural instincts and do not have the Spirit.
James 3:15-16
15 Such “wisdom” does not come down from heaven but is earthly, unspiritual (soulish), demonic. 16 For where you have envy and selfish ambition, there you find disorder and every evil practice.
James 3:17 - 4:10
17 But the wisdom that comes from heaven is first of all pure; then peace-loving, considerate, submissive, full of mercy and good fruit, impartial and sincere. 18 Peacemakers who sow in peace reap a harvest of righteousness.
What causes fights and quarrels among you? Don’t they come from your desires that battle within you? 2 You desire but do not have, so you kill. You covet but you cannot get what you want, so you quarrel and fight. You do not have because you do not ask God. 3 When you ask, you do not receive, because you ask with wrong motives, that you may spend what you get on your pleasures. 4 You adulterous people, don’t you know that friendship with the world means enmity against God? Therefore, anyone who chooses to be a friend of the world becomes an enemy of God. 5 Or do you think Scripture says without reason that he jealously longs for the spirit he has caused to dwell in us? 6 But he gives us more grace. That is why Scripture says: “God opposes the proud but shows favor to the humble.” 7 Submit yourselves, then, to God. Resist the devil, and he will flee from you.8 Come near to God and he will come near to you. Wash your hands, you sinners, and purify your hearts, you double-minded. 9 Grieve, mourn and wail. Change your laughter to mourning and your joy to gloom. 10 Humble yourselves before the Lord, and he will lift you up.
