Let's look into words of Bible on Why we need to worship God ONLY and no others!

2. However this is what, Lord Jesus Christ said in Mathew 4:10 while
replying to Satan when he tempted Jesus to bow down & worship him
-– “Worship the Lord your God, and serve him only”
Mary – yes, the favoured one & blessed among women (Luke 1:28,42)
Apostles(saints) – yes, the most respected and who would be on
throne(s) of Judgement along with God in heaven (Mathew 19:28)
Angels – yes, little higher than humans (Psalm 8:5, Hebrews 2:7)
And in Isaiah 42:8, God says, “I am the LORD; that is my name!
I will not give my glory to anyone else, nor share my praise
with carved idols”

3. And this is what Mary said to people at Cana, just before
Jesus did his first miracle – “Do whatever he(Jesus) tells
you” (John 2:5)

4. The wise men from the east worshipped Jesus only
(though he was ‘just born’ child) and not Mary, his
mother – Mathew 2:11

5. And let’s note Jesus response to a person’s praise of his
mother, in Luke 11:27,28 -- …a woman in the crowd called out,
“Blessed is the mother who gave you birth and nursed you”. Jesus
replied, “Blessed rather are those who hear the word of God and obey it.”
And again when his mother and brothers were wanting to talk
to him while he was speaking to the crowd, in Mathew 12:48-
50 -- But he replied to the one who told him, “Who is my mother? And who
are my brothers?” He reached out his hand toward his disciples and said,
“See, my mother and my brothers! For whoever does the will of my Father in
heaven is my brother and sister and mother.”

6. Peter’s objection over Cornelius falling on his feet and admits
that he's just a man like him – Acts 10:25,26 -- As Peter entered
the house, Cornelius met him and fell at his feet in reverence. But Peter
made him get up. “Stand up,” he said, “I am only a man myself.”

7. Paul & Barnabas declaring that they are just humans like the
audience and advised them not to worship them – Acts 14:15 --
“Friends, why are you doing this? We too are only human, like you. We are bringing
you good news, telling you to turn from these worthless things to the living
God, who made the heavens and the earth and the sea and everything in them”

8. Paul’s warning in Romans 1:22,23 –-
22 Although they claim to be wise, they have become fools 23 In fact, they
have exchanged the glory of the immortal God for mere images, like a mortal
human being, or like birds, animals or reptiles!

9. And do not worship even the angels of God – Testimony of John,
the loved disciple, who was nominated as son to Mary, and she as
mother to John, by Jesus at Cross (John 19:26,27)
# I, John, am the one who heard and saw these things. And when I had heard
and seen them, I fell down to worship at the feet of the angel who had been
showing them to me. But he said to me, "Don't do that! I am a fellow servant
with you and with your fellow prophets and with all who keep the words of
this scroll. Worship God!” - Revelation 22:8,9
# At this I fell at his feet to worship him. But he said to me, "Don't do that! I
am a fellow servant with you and with your brothers and sisters who hold to
the testimony of Jesus. Worship God! For it is the Spirit of prophecy who
bears testimony to Jesus."- Revelation 19:10

10. And the first 2 of the Ten commandments of God states --
1.“You shall have no other gods before me.”
2. “You shall not make for yourself an image in the form of anything in
heaven above or on the earth beneath or in the waters below. You shall
not bow down to them or worship them”
-- Exodus 20: 3,4 (Given through Moses)

11. So we need to worship only our Lord, God of trinity who
revealed to us as “Heavenly Father”, “Jesus Christ” (Son of God)
and “Holy Spirit” (Spirit of God)

12. God bless you
