It is hypocritical to keep the Sabbath while sowing discord among the brethren. It is hypocritical to sing only the psalms while refusing to worship in the way they describe. It is hypocritical to be proud about celebrating the incarnation, which sets an example of humility. It is hypocritical to call Jesus Lord if we do not also seek his sense of justice and mercy. Instrumental in this change is our willingness to spend time with God in prayer, study and other spiritual disciplines.
Worship involves all of life.
We see this especially in the words of Paul. All of life is to be worship, not just a few hours each week. Here we see that preaching the gospel is a form of worship. Financial help given to other Christians can be a form of worship. Although music has been an important part of worship at least since the time of David, music is not the most important part of worship.
