In pagan religion, people worship god out of fear or in order to obtain favors from him.
Christianity is about the True And Living God - Christ Jesus. It is about Truth regarding God's nature and purspose for mankind, individually and collectively.
In pure Christianity we understand that the whole purpose of creation is God's love and Grace. He created us to love us and to bless us. His pleasure is in giving us what He has.
God obtains pleasure when we come into intimate, personal relationship with Him.
God gave Himself as a sacrifice to reconcile us to Himself.
God shed His blood to cover the sin that separated us from Him.
God gave us His Holy Spirit so that we can be One with Him, so that we become partners with Him.
God does not need our worship. He is perfect and complete in Himself.
But we need to worship our benefactor in order to be complete. We are not complete without Him.
Worship brings us into that complete place by honoring Him by whom we exist and by valuing Him who has given all things to us.
To worship our Mighty God, the Lord Jesus Christ, is to be healthy in our core. Out of our healthy core proceeds health in all other areas of our lives.
To not worship one's benefactor is to be patently unhealthy in one's core. To be unhealthy in one's core is to be susceptible to unhealthiness in all other areas of one's life.
Worship of Christ Jesus is therefore eminently practical.
