Galatians 5:13,16-17—For, brethren, ye have been called unto liberty; only use not liberty for an occasion to the flesh, but by love serve one another. This I say then, Walk in the Spirit, and ye shall not fulfill 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.
Christ has set us free from the rules and regulations of the laws delivered to Moses. Now we have a much more comprehensive guideline, the life of the Holy Spirit. Free from the many details of the law can be misconstrued to be indulgence in the sinful nature. It is just the opposite. It is submission to the Spirit of God. In submitting to the Spirit, we love one another with the love of Jesus. We are willing to lay down our lives for one another. Under the law, I could go my own way in selfishness. Under the life of the Spirit, I cannot pass my brother in need. Their need becomes mine. I weep with those that weep. I share what I have with those in need. My life becomes a life of service. If your life flows from the Spirit of God who lives within you, you will not go about trying to gratify your sinful nature. That doesn’t mean you will never fail under temptation, it simply means that the driving force of your life has now changed. You once lived only to gratify self. Now you live for God’s pleasure, and in doing so love your neighbor as yourself. The sinful nature and the Spirit have opposing desires. You can’t live for them both at the same time. It will put your soul into conflict. One or the other will win out. New creations in Christ do not desire to fulfill their sinful nature’s desires. When they fail and do so, they realize it was not what they wanted. If the sinful nature’s desires are still what you truly want, you have yet to surrender to the Spirit and become a new creation in Christ. Ask Him to take over the very desires of your heart. Claim the many promises given to those who call on Jesus. They promise a new heart to those who call on Him.
