God has always commanded mankind to worship Him. The fact that God commands it should be reason enough to do it. However, simply worshipping God out of a sense of duty can cause us to lack in sincerity (John 4:24). There are other reasons for worshipping God other than it being commanded. One who is properly motivated by those reasons will worship God in a way that will be acceptable to Him. So, why should we worship God?
To express love and thanksgiving to God. By its very nature, worship is to be an expression of love and devotion. Our love for God, based upon who He is and what He has done for man, should prompt us to worship Him. John says that we love God because He first loved us (1 John 4:9). The great love of God should cause us to give thanks for His indescribable gift (2 Cor. 9:15).
To express our desire to submit to the will of God. As we have already discussed, God has commanded His children to worship Him (Heb. 10:24-25). By our obedience to this command, we show our willingness to be submissive to God’s will. Which, is a necessity in order to please God (Matt. 7:21). We must remember that God’s will is for man’s ultimate good. Our submission to His will acknowledges His superior wisdom.
To set a good example for those outside of Christ. Dedication to Christ and our devotion to worship makes an impression upon others. When we are faithful in our attendance and active in the worship services, we show others how important the Lord is to us. We must remember that it is possible to lead others to Christ through a good example and strong influence of dedicated worship to God (1 Pet. 3:1-4).
There are other reasons that could be given for us to worship God. We should worship to stay saved, to learn, to provide a source of strength for others, and to edify each other. May we use all of these reasons as motivation to worship the One who so deserves it!
