The Hebrew word most often used in the Old Testament for "worship" means "bow and indicates a humble submission like a servant to his master ( Genesis 33:3 ). In the New Testament, the Greek word that is most often used, " proskuneo " means " an act if respect" (Mathew 8:2, 18:26).
The same idea arises when we talk about the worship of God by man. We humble ourselves before our creator, with an attitude of reverence to God, to honour, serve and fear him for who he is and the expression of admiration of his majesty.
Worship is not only what we do at church. It is not only beautiful songs moving music, which constitute external worship.
Worship has nothing to do with style, volume or speed of a song.
True worship that is pleasing to God is the total, complete and joyous giving of the creature to his creator. It is expressed throughout our life in a life of holiness. It is about trusting him, loving him, obeying him, helping our neighbor for his sake etc. It is not limited to religious buildings. It must have priority over anything else. It is a matter of a heart on fire for God. It is a completely selfless act. We do not worship God to have something in return.
The responsibility of any intelligent creature, the first purpose of our life, is to worship God (Rev4:10-11, 14:7). Angels worship him (Neh 9:6). His saints admire him. And soon all the earth shall worship him (Psalm 86:9, Rev 7:8-12). The Father seeks true worshipers, those who worship in spirit and in truth (John4:23-24).
