This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh. For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would. (Galatians 5:16-17)
For the lost person, who is not a child of GOD you cannot walk in the Spirit of GOD because you do not yet have the Spirit. You only exist in the flesh, and are still at war with GOD. He calls you to surrender to Him on His terms, and He as Creator has the right to do so. He loves you enough that He came as a man, and went to a cruel Roman cross to pay for your sins. Receive Him that you will have eternal life, not just fire insurance, but a relationship with a Holy and righteous GOD who loves you and wants you to be saved.
Respond in obedience to Him today.
