What does it mean that God demands proper worship?

God's demand for proper worship emphasizes that worship is not simply about sincerity or human effort; it must adhere to the divine standards He has set. Examples from Scripture, such as the deaths of Nadab and Abihu for offering strange fire, illustrate that deviating from God's prescribed methods of worship is unacceptable. When approaching God, it is critical that our worship aligns with truth and acknowledges Christ's substitutionary atonement. Worship that does not do this is considered false and, ultimately, is detrimental to the soul. Thus, God’s demand for proper worship calls believers to understand and engage in worship that honors His holiness and achieves His purposes.
