Nadab and Abihu were priests who were to respect and honor God’s law. In an attempt to burn incense to God, both Nadab and Abihu were killed by God because they failed to follow God’s will (Lev. 10:1, 2). They were doing the right thing (burning incense) at the right place (tabernacle) for the right reason (praise God). However, they used the wrong fire.
Some today believe it is acceptable to alter God’s will concerning musical worship. He commanded the church to sing (Eph. 5:19; Col. 3:16). There are men who change this to sing and play, and believe God will accept it. What do you think Nadab and Abihu would say?
Some today believe it is admirable to preach salvation by faith alone, despite the fact that God said salvation is “not by faith only” (Jas. 2:24). Faith is required (Heb. 11:6; Mk. 16:16). However, faith alone is dead (Jas. 2:26). The Bible teaches salvation is by faith, repentance, confession of Christ, and immersion in water for the remission of sins (Rom. 10:9, 10; Acts 2:38; 22:16). A change in God’s plan for saving man is a gross violation of His will. Do you suppose Nadab and Abihu would warn men not to make such changes?
