As you therefore have received Christ Jesus the Lord, so walk in Him, rooted and built up in Him and established in the faith, as you have been taught, abounding in it with thanksgiving.
In the same manner in which you received Jesus as your Lord and Saviour, you are to walk in Him. How did you receive Jesus? How did you get saved from sin and set free? Was it by any great works on your part? No! You received Jesus by believing in Him, you received Him through faith.
But what does it say? “The word is near you, in your mouth and in your heart” (that is, the word of faith which we preach): that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation. For the Scripture says, “Whoever believes on Him will not be put to shame.” For there is no distinction between Jew and Greek, for the same Lord over all is rich to all who call upon Him. For “whoever calls on the name of the Lord shall be saved.”
For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast.
For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.
You received Jesus through faith and not by works, and so you should continue to walk in Him by faith, not switching over to works to try and please God. How then do we live a holy life? True and lasting holiness comes by living out of our redeemed born-again spirit, not by following a set of external rules.
I say then: Walk in the Spirit, and you shall not fulfill the lust of the flesh. For the flesh lusts against the Spirit, and the Spirit against the flesh; and these are contrary to one another, so that you do not do the things that you wish. But if you are led by the Spirit, you are not under the law.
If we live in the Spirit, let us also walk in the Spirit.
The Jews under the Law of Moses, tried to live according to a set of rules and failed. If we are born-again, we are a new creation, the old sinful us is dead and a new sin free man lives inside of us. We have a new nature, we are no longer sinners but righteous saints (2 Cor 5:21). As you get a revelation of this fact, you can start to live free from sin and live holy by nature. This is walking in faith, walking in all Jesus has done for you.
Trying to live by the rules through willpower rather than out of your new born-again nature, will actually cause you to sin more!
1 Corinthians 15:56
The sting of death is sin, and the strength of sin is the law.
Therefore by the deeds of the law no flesh will be justified in His sight, for by the law is the knowledge of sin.
knowing that a man is not justified by the works of the law but by faith in Jesus Christ, even we have believed in Christ Jesus, that we might be justified by faith in Christ and not by the works of the law; for by the works of the law no flesh shall be justified.
2 Corinthians 5:17
Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new.
What shall we say then? Shall we continue in sin that grace may abound? Certainly not! How shall we who died to sin live any longer in it? Or do you not know that as many of us as were baptized into Christ Jesus were baptized into His death? Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life. For if we have been united together in the likeness of His death, certainly we also shall be in the likeness of His resurrection, knowing this, that our old man was crucified with Him, that the body of sin might be done away with, that we should no longer be slaves of sin. For he who has died has been freed from sin. Now if we died with Christ, we believe that we shall also live with Him, knowing that Christ, having been raised from the dead, dies no more. Death no longer has dominion over Him. For the death that He died, He died to sin once for all; but the life that He lives, He lives to God. Likewise you also, reckon yourselves to be dead indeed to sin, but alive to God in Christ Jesus our Lord. Therefore do not let sin reign in your mortal body, that you should obey it in its lusts. And do not present your members as instruments of unrighteousness to sin, but present yourselves to God as being alive from the dead, and your members as instruments of righteousness to God. For sin shall not have dominion over you, for you are not under law but under grace.
You are dead to sin and alive to Jesus. Realise that you are free, you are no longer a slave to sin and live out of that position of freedom. Then you will find that when sin knocks on your door, that you will be able to say, that’s not me, I’m not interested in that.
Read the book of Galatians, it’s all about how the Galatian church received Jesus through faith but then fell into a performance mindset, working to please God. The Apostle Paul corrected them strongly, pointing out that what they were practicing was no longer the true Gospel of Jesus!
