Luke 14:34 Salt is good: but if the salt have lost his savour, wherewith shall it be seasoned?
Luke 14:35 It is neither fit for the land, nor yet for the dunghill; but men cast it out. He that hath ears to hear, let him hear.
Salt in the natural is a preservative or it is used to flavor food. Losing it's savor refers to it not being useful for food. It has no value, but is to be thrown out. What of salt in the spiritual? When Jesus was asked if he had anything to eat, he replied : "My meat is to do the will of him that sent me, and to finish his work." (John 4:34)
Spiritual meat is to do the will of God. So what is spiritual salt? The Holy Spirit is a restrainer of wickedness; perhaps spiritual salt is holiness. Not much is said in today's churches about holiness. But to lose your witness and testimony is to be useless to the kingdom of God and useless in the eyes of the world. Are we living a holy life before God and the world?
Lev 18:26 Ye shall therefore keep my statutes and my judgments, and shall not commit any of these abominations; neither any of your own nation, nor any stranger that sojourneth among you:
Lev 18:27 (For all these abominations have the men of the land done, which were before you, and the land is defiled;)
Lev 18:28 That the land spue not you out also, when ye defile it, as it spued out the nations that were before you.
The church likes to talk about prosperity, but it should be of the Spirit.
Rev 3:16 So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of my mouth.
Rev 3:17 Because thou sayest, I am rich, and increased with goods, and have need of nothing; and knowest not that thou art wretched, and miserable, and poor, and blind, and naked:
We must be commited to walk in the Spirit of the Lord. Our flesh will fail, but if we are in Christ he gives us grace to continue. We are adopted children of God for His good pleasure.
Phil 2:13 For it is God which worketh in you both to will and to do of his good pleasure.
Phil 2:14 Do all things without murmurings and disputings:
Phil 2:15 That ye may be blameless and harmless, the sons of God, without rebuke, in the midst of a crooked and perverse nation, among whom ye shine as lights in the world;
