What does worship the Lord mean? Answer: Honoring the Lord, showing reverence to Him by demonstrating your feelings or expressions of reverence and adoration for the Lord. Why should you worship the Lord? God created the world you live in, He created mankind, animals, birds, the sun, the moon, the oceans, and everything in the world. He breathed life into you and He sent His only Son to die for your sins and the Holy Ghost to live inside of you to guide you and teach you all things. He is not just a King but He is the Most High and deserves to be worshiped by us and to be served by us. When you serve and worship the Lord He will bless your bread and your water. He will remove sickness from you.
Give unto the LORD the glory due unto his name; worship the LORD in the beauty of holiness. Psalms 29:2
Serve the LORD your God, and he will bless your bread and your water. I will remove illnesses from you. Exodus 23:25
