What are the forms of worship?
There is only one form of worship and one true God to worship. The only Book that is worthwhile in knowledge, is the Bible, which is a library of 66 Books.
2 Timothy 3: 16,17 explains the origin of the Bible and why it is beneficial for mankind.
It reads: "All Scripture is inspired of God and beneficial for teaching, for reproving, for setting things straight, for disciplining in righteousness, so that the man of God may be fully competent completely equipped for every good work.
The Book of Isaiah 48: 17 shows how God presented himself to mankind, in these words. " I. Jehovah, am your God, The One teaching you to benefit yourself.
Isaiah 45: 18 reads: " I am Jehovah, and there is no one else.
It also confirms that He is the One who formed the earth, its maker who firmly established it, who did not create it simply for nothing, but formed it to be inhabited.
John 4: 23 shows what kind of worhippers God is looking for. It shows that true worshippers will worship the Father with spirit and truth, for indeed, the Father is looking for ones like these to worship him.
Which means that those who desire to gain God's approval should walk in his truth and serve him in truth. Read Joshua 24: 14; 1 Samuel 12: 24; Psalms 25: 4,5; 26: 3-6; 43: 3; 86: 11; Isaiah 38: 3.
This would include abiding by God's requirements and serving him in faithfulness and sincerity.
John 17: 3 shows that worshipping God according to his requirements is lifesaving. The first couple lost that priviledge due to the fact that they chose to listen to some other voice, with deadly consequence for mankind. Read Genesis 3: 1-5; 16-19; Romans 5: 12.
However, God did not give up on the human race. 1 Corinthians 15: 22 reads: " For just as in Adam all are dying, so also in the Christ all will be made alive. Which was accomplished 2'000 years ago, when he sent his precious Son to earth to redeem the humans race from the curse of sin and death and to undo the damage caused by Satan in the garden of E'den.
Read John 3: 16; 1 John 3: 8.
So to answer your question. There is only one true God and one way to worship him, which is with truth and action in harmony with his requirements.
The Book of James 1: 22 reminds us to become doers of the word and not hearers only.
