The word WORSHIP in the Hebrew is 'Shacha' and it means to depress, i.e. prostrate (especially reflexive, in homage to royalty or God), bow (self) down, crouch, fall down (flat), humbly beseech, do (make) obeisance, and do reverence.
One thing is clear from the definition above; worship means to bow oneself to God. To successfully do this, a person needs to be humble at heart; this is only possible when one first acknowledges that God is greater than them.
This is important because there can be no worship without first bowing oneself to God. Each time any of God’s creations does this, they give Him great pleasure.
I want to emphatically state that when Abraham went yonder with his son Isaac to WORSHIP God, there were no musical instruments present and no moods needed to be activated.
Abraham’s worship was not a momentary activity; it was the fruit of decades of obedience to God – a lifestyle. It was not an emotive undertaking (had Abraham deferred to his emotions, he would not have obeyed God), it was a covenant commitment to God. Also, God was more interested in Abraham’s obedience than in his sacrificing Isaac. In obeying God, Abraham gave God great pleasure.
