“Don’t be misled—you cannot mock the justice of God. You will always harvest what you plant. Those who live only to satisfy their own sinful nature will harvest decay and death from that sinful nature. But those who live to please the Spirit will harvest everlasting life from the Spirit” (Galatians 6:7-8, NLT).

Do not be deceived: God cannot be mocked. A man reaps what he sows. Whoever sows to please their flesh, from the flesh will reap destruction; whoever sows to please the Spirit, from the Spirit will reap eternal life” (Galatians 6:7-8, NIV).

What does Paul means by this statement? Does he mean that salvation is earned by work of law? Does it mean that the death of Christ is now in vain? Is salvation no longer earned by faith through grace?

Literal interpretation of this verse of the bible will suffice to mean that salvation is earned or merited by simply obeying, or keeping the law. Thus, those who do the work of the law are the ones working in the spirit while those who live in grace now walk in the flesh. Notice that King James Version, put verse 8 as, for he that soweth to his flesh shall of flesh reap corruption; but he that soweth to the spirit shall of the spirit reap life everlasting. (Galatians 6: 8 KJV). 

First and foremost let us not be confused here salvation is a free gift to all who believed in the death of Christ and takes a further step by making him (Jesus) Lord over his life. For God so loved the world that He gave his only begotten son, that whosoever believe in Him shall not perish but have everlasting life. For by grace are you saved through faith. Thus, salvation comes through God's grace by faith in the death of Christ. In that while we are still in sin Christ died for us, before we were born to this world, Christ has paid the prize. (John 3:16; 4:10; 4:24, Romans 3:24; 5: 8; 8:1, , Galatians 2:16; 3:6-14, Ephesians 2:8-9, Titus 3:5-7, Revelation 1:5; 22:17).

 Before this verse Paul wrote,  “Yet we know that a person is made right with God by faith in Jesus Christ, not by obeying the law. And we have believed in Christ Jesus, so that we might be made right with God because of our faith in Christ, not because we have obeyed the law. For no one will ever be made right with God by obeying the law…. I do not treat the grace of God as meaningless. For if keeping the law could make us right with God, then there was no need for Christ to die” (Galatians 2:16,21, NLT; Steve. C).

Can God words contradict each other? Never! The bible is very clear on the issue of grace and law. Naturally, human beings are unable to keep all do do's and don't of the law because of the falling nature of man. But, the grace to live a righteous life was given to man through the death of Christ, simply by living the life of Christ on earth. To live the life of Christ comes through grace by faith in Christ.

Back to the text, the scripture in Galatians 6: 7, clearly indicates that there is sowing period and reaping/ harvest time. So what determines what you reap is what you sow. Salvation has been freely given to all by the death of Christ, but not all will embrace it. Jesus says, if you love me keep my commandment (John 14:15). No man ever reaped what he didn't sow, rather where they sow. Jesus said, where your treasure is there your mind will be (Mathew 6:21). Jesus said, narrow and straight is the gate and only few find it.  

Sowing to the flesh can otherwise be referred as living according to the dictates of the flesh, living to gratify the flesh rather than God. For you have been saved and free from the works of the flesh, you are dead to your flesh and alive to Christ to walk according to the dictates of his spirit that lives inside you. He who walk according to the dictates of the spirit of Christ living in us is not condemned but have eternal life. So eternal life must be labored for by way of disciplined, self-control, spiritual exercises, forsaking the world and it vices. {Roman 8:1, 1 Corr. 9:24-27, Matt. 7: 14, Luke 14: 26, 33).   

Jesus while teaching links faithfulness in serving Him with experiencing an eternal life (Matthew 19:29). We are all Christ ambassador on earth, we represent Him here on earth and anybody that must earned reward at last must be faithful in his service. He who lives after his flesh sow in his flesh and will receive his reward here on earth and eternal condemnation. If we are hard working in our service for the Lord, we will reap treasure in the kingdom of heaven (2 Timothy 2:4-8, Matthew 6:19-21). If we are lazy or disobedient in our Christian lives, we will reap no treasure. Rather, we will reap rebuke by the Lord Jesus (Luke 19:22-26). 

Every time we allow our mind to harbor a grudges against others, nurse a grievance, entertain an impure fancy, wallow in self-pity, being carried away by envy, we are sowing to the flesh. Every time we linger in bad company whose insidious influence we know we cannot resist, every time we lie in bed when we ought to be up and praying, every time we read pornographic literature, every time we take a risk that strains our self-control we are sowing, sowing, sowing, to the flesh.

But those who live to please the Spirit will harvest everlasting life from the Spirit

Living to please the spirit is to walk in love. And the bible recorded in Romans 13: 8, that he who love his neighbor as himself has fulfill the law. So to live in the spirit is to live for Christ where Living for Christ entails doing those things Christ would have been doing if present on the earth. We are his Ambassador so our life should reflect him, people should be able to see Christ in our lifestyle without been told. We ought to preach the gospel of love to as many as we can, we ought to baptize people into the doctrine of Christ. 

Our focus and thought always should be how to please God and how to show love to our neighbors. When you are busy thinking of what next you will do for God because of your love for him, you can't start thinking of how to satisfy yourself. Because of your love for Jesus, you will always be interested in praying for the lost souls even when you have so many unanswered prayers. Your love for Christ will prompt you to care for others selflessly just as Jesus cares for them.

Because of your love for Christ that comes by walking in Spirit, you will be interested in the growth of the body of Christ (Church). Your love for Christ will triggers you to give tirelessly to the work of Jesus, your love for Christ will make you to pay your tithes and gives offering willingly without being persuaded. Anything you do for people to notice you is not done in the spirit but rather in the flesh. The flesh often seek His own glory, notice me while the spirit seek the glory of God only.

Note also, that the spirit and the flesh are always in war over who you must please, the spirit been gentle while the flesh is arrogant and doesn't take chances. The flesh is interested in you feeding, pleasing your body while the spirit is interested on you feeding your soul. The spirit enjoys pleasure-pleasing our own self but the spirit enjoys dedication to the service of God. While the flesh loves enjoyment and rest here on earth, the spirit enjoys dedication and recognizes only rest in heaven.

So as Christians we should all labor hard while still on earth while we still have all the time, because night is coming when no man can work, and we all shall stand to give account of our labor during the day.
