The Torah is the first five books of the Old Testament. Some Christians hate the law. They say that we live under grace, not law. However, those making this statement should be clear what parts of the Torah are no longer relevant. Jesus had a fairly serious warning for those who reject the Torah.
Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished. Anyone who breaks one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven (Matt 5:17-19).
The Torah covers a variety of topics. We need to be clear about which parts have been fulfilled, and which parts remain in force.
- civil laws,
- tabernacle design,
- infection control and hygiene,
- blessings and curses,
- rules for priesthood
- land distribution
The tabernacle and the sacrifices have been fulfilled by Jesus death on the cross. They sacrifices never did provide salvation from sin, but needed to be accompanied by faith to be effective. The tabernacle has been replaced by the body of Christ becoming the temple of the Holy Spirit.
The genealogies remain, but are not so relevant for the gentiles. The Aaronic priesthood has been replaced by the priesthood of all believers. We are all priests and kings.
The civil laws have not been fulfilled or set aside by Jesus. Modern society contains sinful people, so civil laws are still needed. The only issue is how we implement them. The answer is godly judges.
