As a believer in Christ you are no longer a slave to sin. To understand this, lets read John chapter 8 verses 31 to 35
31 So Jesus said to the Jews who had believed him, “If you abide in my word, you are truly my disciples, 32 and you will know the truth, and the truth will set you free.” 33 They answered him, “We are offspring of Abraham and have never been enslaved to anyone. How is it that you say, ‘You will become free’?” 34 Jesus answered them, “Truly, truly, I say to you, everyone who practices sin is a slave to sin. 35 The slave does not remain in the house forever; the son remains forever. 36 So if the Son sets you free, you will be free indeed.
You are called to be free, no longer a slave. Slavery to sin is the worst of all. Because this slavery continues in hell for all eternity. Only the Son of God can set you free from sin and death.
You are called to be with God forever as his child. Though it’s a great honor to be an angel of God it’s even a greater honor to be in truth a child of the Lord God.
Now let’s read Galatians chapter 4 verses 1 to 7
1I mean that the heir, as long as he is a child, is no different from a slave, though he is the owner of everything, 3but he is under guardians and managers until the date set by his father. 3 In the same way we also, when we were children, were enslaved to the elementary principles of the world. 4 But when the fullness of time had come, God sent forth his Son, born of woman, born under the law, 5 to redeem those who were under the law, so that we might receive adoption as sons. 6 And because you are sons, God has sent the Spirit of his Son into our hearts, crying, “Abba! Father!” 7 So you are no longer a slave, but a son, and if a son, then an heir through God.
Jesus redeemed you from the curse of the law so that you get adopted as a child of God. So never think of Christianity as following a set of laws. It’s about being a right relationship with God through Jesus. You need to believe in the Gospel.
Let’s read Romans chapter 8 verses 12 to 17
12 So then, brothers, we are debtors, not to the flesh, to live according to the flesh. 13 For if you live according to the flesh you will die, but if by the Spirit you put to death the deeds of the body, you will live. 14 For all who are led by the Spirit of God are sons of God. 15 For you did not receive the spirit of slavery to fall back into fear, but you have received the Spirit of adoption as sons, by whom we cry, “Abba! Father!” 16 The Spirit himself bears witness with our spirit that we are children of God, 17 and if children, then heirs—heirs of God and fellow heirs with Christ, provided we suffer with him in order that we may also be glorified with him.
You are called to no longer live by the works of the flesh. But rather be led by the Holy Spirit. The Holy Spirit will remind of you of the things of God. He bears witness that you are a child of God. Do not therefore worry about your sins but repent of them. Be free not for evil but for the Lord Jesus who loves you so much.
