John 4:23-24
But a time is coming and has now come when the TRUE worshippers will worship the Father in spirit and in truth, for the Father is seeking such as these to worship Him. God is Spirit, and His worshipers must worship Him in spirit and in truth.
At its very root, worship is our response to God's worth. It is acknowledging that God's character is greater than our circumstance. God is deserving of our unrelenting devotion even when our feelings say otherwise. Worship is saying “we will not forget Your works! We lift our eyes up to where our help comes from. Because we know the strength and victory is in You!” When we tap into that understanding of worship we will see our whole world view begin to shift. We will change how we love people, because God is Love. We will change how we relate to our children because God is the perfect Father. We will change how we work at our job because we want our work to be a reflection of His Greatness. Set aside the idea that worship is four songs and a sermon once a week. Worship is our day to day realization that God is good and always worthy of praise. Sunday mornings are simply an overflow of time in the secret place with God.
Before the Lord helped King David slay Goliath, David slayed bears and Lions in the fields by himself watching the sheep. He remembered God's works, and that gave him the strength to slay Goliath. Psalm 78:9-11 says “the children of Ephraim (meaning fruitfulness or strength) turned back on the day of battle. They did not keep God's covenant, but refused to walk according to his law. They forgot his works and the wonders that He has shown them.” When we set our minds on His worth and remember all of the things God has done for us, that is where we get our strength and that's when we truly worship.
