In the Old Testament the sacrificial fire “came forth from Jehovah.” This altar fire was ignited by God and was to continuously burn (Lev 6:12-13). For 40 years wherever the tabernacle was moved in the desert wanderings, worship was offered in sacrifices by this divine fire. When two priests, sons of the high priest, offered “strange fire,” not the prescribed altar fire, they were put to death “by fire from Jehovah” (Lev 10:1-2). The Bible speaks several times about these religious leaders, Nadab and Abihu. Moses quoted Exodus 14:4 to their father Aaron: “Among those who approach me I will show myself holy; in the sight of all the people I will be honored.” Aaron remained silent. Jesus said those who love Him keep His commandments (Jn 15:14). Paul wrote that “keeping commands of God is what counts” (I Cor 7:19) and that the examples in the Old Testament were written for our warning (Rom 15:4; I Cor 10:6-12). Notice: When God said for Christians to sing praises to Him, to substitute or add mechanical instruments or rhythmic clapping or dancing is without authority. Ask for FIRE booklet by Brassfield.
