The first thing to learn about worthy worship is that worship should be in accordance to the commandments of God, but it should not be mechanical. In other words, obedience must precede any act of worship and it must come from the depth of our being. 1 Samuel 15:22 says,
“And Samuel said, Hath the LORD as great delight in burnt offerings and sacrifices, as in obeying the voice of the LORD? Behold, to obey is better than sacrifice, and to hearken than the fat of rams.”
Any worshipper who is not living in obedience to the word of God worships in vain. Of such are Christians who call Jesus “Lord, Lord”, but fail to do the will of God. Their effort is fruitless and their act of worship does not move God. You will not worship God in vain in Jesus’ Name.
 
Any act of worship that is mechanical, devoid of true love, faith, reverent adoration, honour, and praise to the Almighty God will not be acceptable. Worship that is worthy and acceptable to God must be offered in spirit and in truth; it must be offered wholeheartedly and with total submission to the will of God. In Matthew 22:37, Jesus enjoined us to love the Lord with all our heart, soul and might; this means that worthy worship requires putting in everything we have. The right attitude is required for our worship to be counted worthy and acceptable to God. The first step is to carry out a self-examination to be sure that our heart is right with God (1 Corinthians 11:28). Then we are to carefully follow the footsteps of David in 2 Samuel 12:20a:
“Then David arose from the earth, and washed, and anointed himself, and changed his apparel, and came into the house of the LORD, and worshipped:”
 
David got up from the earth; this means he separated himself from earthly things. Next, he washed up to properly cleanse himself from every form of dirt and iniquity. He proceeded to anoint himself and change his filthy garments to that of holiness and righteousness. Only then did he have the confidence to enter the presence of God and was able to worship God without any hindrance. As you approach the presence of God today, your worship will be counted worthy and acceptable before Him in Jesus’ Name.
