We Belong To God

"And when they came to him, he said to them:

“You yourselves know how I lived among you the whole time from the first day that I set foot in Asia, serving the Lord with all humility and with tears and with trials that happened to me through the plots of the Jews; how I did not shrink from declaring to you anything that was profitable, and teaching you in public and from house to house, testifying both to Jews and to Greeks of repentance toward God and of faith in our Lord Jesus Christ. And now, behold, I am going to Jerusalem, constrained by the Spirit, not knowing what will happen to me there, except that the Holy Spirit testifies to me in every city that imprisonment and afflictions await me. But I do not account my life of any value nor as precious to myself, if only I may finish my course and the ministry that I received from the Lord Jesus, to testify to the gospel of the grace of God." (Acts 20:18-24 ESV)

"So you also must consider yourselves dead to sin and alive to God in Christ Jesus.
Let not sin therefore reign in your mortal body, to make you obey its passions. Do not present your members to sin as instruments for unrighteousness, but present yourselves to God as those who have been brought from death to life, and your members to God as instruments for righteousness. For sin will have no dominion over you, since you are not under law but under grace."
(Romans 6:11-14 ESV)

"For none of us lives to himself, and none of us dies to himself. For if we live, we live to the Lord, and if we die, we die to the Lord. So then, whether we live or whether we die, we are the Lord's."
(Romans 14:7-8 ESV)

The Lord Is Sovereign to Each Believer
“The third reason every Christian should accept every other Christian is that the Lord Jesus Christ is sovereign to each believer. Whether strong or weak, a sincere believer feels free or not free to do certain things out of the same motive: to please his Lord. Neither one is more or less spiritual or faithful because of his convictions about practices such as those discussed above. Being “strong” in this sense is not synonymous with being spiritual, and being “weak” is not synonymous with being carnal. The problem in the church at Rome, as in many churches since that day, was that some believers of both persuasions thought themselves to be more spiritual and the others to be more carnal. Paul’s whole purpose in these verses, and in the larger context of (14:1–15:13), was to disabuse believers of those false, divisive, and destructive notions.” John MacArthur. Romans Commentary.

"For the love of Christ controls us, because we have concluded this: that one has died for all, therefore all have died; and he died for all, that those who live might no longer live for themselves but for him who for their sake died and was raised."  (2 Corinthians 5:14-15 ESV)

We are not the rulers of our lives, Jesus is. We are told that we belong to God and therefore a thing as simple as what we eat for lunch must be weighed against what would be in keeping with the glory of God.
