1) Direct Answer
Because Jesus fulfilled the Law and brought in the New Covenant. The parts of the Old Testament that were shadows and rituals for Israel’s worship ended at the Cross, but the moral righteousness of God remains and is written in our hearts by the Holy Spirit. So we don’t “pick and choose”—we follow what the Bible itself carries forward in the New Testament and what it says has been fulfilled.

2) Scriptural Explanation
- “Think not that I am come to destroy the law… I am not come to destroy, but to fulfill” (Matthew 5:17).
- “Blotting out the handwriting of ordinances that was against us… nailing it to his cross… Let no man therefore judge you in meat, or in drink, or in respect of an holyday… or of the sabbath days: Which are a shadow of things to come; but the body is of Christ” (Colossians 2:14-17).
- “The law having a shadow of good things to come” (Hebrews 10:1).
- “The law was our schoolmaster to bring us unto Christ” (Galatians 3:24).
- The New Testament repeats God’s moral commands: “Thou shalt not commit adultery… kill… steal… bear false witness… covet… and if there be any other commandment, it is briefly comprehended in this saying… Thou shalt love thy neighbour as thyself” (Romans 13:9).
- Concerning food laws: Jesus declared what enters the man does not defile him (Mark 7:18-19), and “every creature of God is good… sanctified by the word of God and prayer” (1 Timothy 4:4-5).
- Concerning sabbath days and feast days, the Scripture calls them “a shadow,” and says not to be judged in them (Colossians 2:16-17). Our true rest is entering into Christ (Hebrews 4:9-10; Matthew 11:28-29).
- Concerning circumcision: “He is a Jew, which is one inwardly; and circumcision is that of the heart” (Romans 2:29; see also Colossians 2:11).
- The apostles, by the Holy Ghost, laid only necessary things on Gentile believers (Acts 15:28-29), showing that the Mosaic ritual was not binding on the church.

3) Simple Clarifying Logic
Now notice how the Bible itself makes the line clear:
- Temple/ceremonial laws (sacrifices, priesthood, feast days, dietary and purity rituals) were shadows pointing to Christ. When the Lamb of God came and shed His blood, the sacrifices and priestly system reached their fulfillment (Hebrews 10:1-14). To keep the shadow after the substance has arrived would deny the very fulfillment.
- Civil/national laws (land rules, penalties, kingship statutes) governed Israel as a nation. The church is not a political nation; our Kingdom is not of this world (John 18:36). We submit to civil authorities where we live (Romans 13:1-7), but the church does not enforce Israel’s state penalties.
- Moral law (God’s holy character—no idolatry, no murder, no adultery, no stealing, truthfulness, purity, love) never expires. The New Testament reaffirms and even lifts it higher—anger judged as murder in the heart, lust as adultery in the heart (Matthew 5:21-30). Under grace, the righteousness of the law is fulfilled in us who walk in the Spirit (Romans 8:4). God writes His law on our hearts (Hebrews 8:10).

You see, it’s not three Gods and it’s not two Bibles. It’s one God unfolding His covenant. The shadow gives way to the substance, but the holy nature of God remains the same. That’s why we still reject sin but we don’t keep animal sacrifices, temple rituals, or feast-day obligations. Christ fulfilled them.

4) Reinforcing Statement
So the reason some Old Testament laws are kept and others are not is simple: the Bible says the shadows ended in Christ, and the New Testament repeats and deepens the moral commands. We’re not under the letter that kills, but under the Spirit who writes the law within and leads us to live holy.
