Not all worship is accepted by God.
This is why we encourage our church family every Friday evening/Saturday to prepare their hearts for The Lord’s Day BEFORE coming into the gathering. It’s not only important to faithfully attend the gathering of the body on the Lord’s Day, but it’s essential that we do so with a Gospel-centered heart focused on the Lord our God, King of the Universe, Creator, and Savior of our souls — or it’s self-worship.
God killed two priests in the Bible for using incense that was not prescribed by God for worship.
Just because we “feel” like our worship is worship, it doesn’t mean our worship is accepted by God as worship. Neither our heart nor our mind defines worship.
God defines acceptable worship. He reveals what acceptable worship is in His holy, living, complete, authoritative Word in what we call The Bible.
Sola Scriptura.
