There is only one person to whom we have to give the full authority and to whom we have to give our ear and heart fully.
Jesus, been tempted could resist and said to the Devil, "Be on your way, Satan, for it has been written, ‘You shall worship YHWH/Jehovah your God and to Him only shall you render divine service.’"" (Mt 4:10)

Your God: By this Jesus infers that YAHWEH or Jehovah is his God otherwise the quote makes no sense as a response to Satan. Over two dozen times the Scriptures use phrases indicating the Nazarene worships his own God. "The God of our Lord." (#Ephesians 1:3, 17)

It is only to Jehovah that we have to render divine service (The Greek is LATREUSEIS. Or, KJV: serve; RHM: divine service)
We have to fear the LORD of Lords, our God, and serve him, (De 6:13) and should listen to His wishes and His commandments.

By serving God, Jesus obtained all the earthly authority which the devil offered him, and heavenly authority in addition thereto (#Mt 28:18). So much better are the rewards of God than Satan’s.

The words "him alone thou shalt serve" need be recalled today. Jesus warned men against trying to serve God and mammon (#Mt 6:24). Jehovah had previously also brought His penalties over those who did not want to listen. Jehovah gave indications that it was time to act. Also several prophets and Christian writers warned people. "Elijah came near to all the people, and said, "How long will you waver between the two sides? If the LORD is God, follow him; but if Baal, then follow him." The people answered him not a word." "(1Ki 18:21 HNV)

Evil or the devil, as the lord of the evil world, constantly tries to win men to the service of the world and God. This is his chief camouflage for destroying a preacher’s power for God. (The word in (#Mt 4:10) for serve is latreuseiv from latriv a hired servant, one who works for hire, then render worship.

Lots of people are in a position they feel secure because they take no parts. They are sometimes with a denomination, though they have a lot of things they do not keep up to the rules of that denomination. (Compare in the RCC where the Pope has given a lot of rules, but which the majority neglect) A lot of the actions and feasts they hold are pagan and contrary to the Biblical teaching. We do have to ask the question "How long shall we halt between two opinions?" If the LORD is God, follow him; but if Baal, then follow him. (1Ki 18:21 JB2000)

We have to come out of the world the Earthly Matters, the World of Babylon the Great. We should not be partakers of her sins. (Re 18:4)

We should not afraid of them that kill the body, but are not able to kill the soul: but rather fear Him who is able to destroy both soul and body in hell. (Mt 10:28)

Let our seed be sown in good soil, so that we really can hear the right message and understand the Words of God, given to us by the Holy Scriptures. By choosing a denomination who keeps closer to the truth then others, we ourselves can protect ourselves more. By choosing the right religion we can become blessed and become productive. (Mt 13:23)

Keep watch on yourselves, or your hearts will become dulled by carousing, drunkenness and the worries of everyday living, and that Day will be sprung upon you suddenly like a trap! For it will close in on everyone, no matter where they live, throughout the whole world. Stay alert, always praying that you will have the strength to escape all the things that will happen and to stand in the presence of the Son of Man. (Lu 21:34-36)
