In discerning the applicability of biblical law today, two key principles guide our understanding. First, does the law define sin? God's law, scattered throughout the entire Bible, serves to identify sin as any failure to meet His standard, encompassing all unrighteousness. This broad definition applies to us, as the Old Testament, including Genesis through Deuteronomy, was written with the New Covenant church in mind, not solely for ancient Israelites. Second, is there a scripture that definitely states a specific law no longer needs to be physically observed? The Bible reveals a progression from the letter of the law to its spiritual intent, often broadening and sharpening its application over time, always rooted in love toward God and fellow man. Certain laws, such as the sacrificial system, were temporarily imposed under the Old Covenant, as seen in Jeremiah 7:22-23, where God did not initially command sacrifices when bringing Israel out of Egypt but later added them due to transgression. Hebrews 9:8-10 and 10:1-4 clarify that these ceremonial laws, including sacrifices and washings, were set aside with the coming of Christ, whose superior sacrifice replaced them with eternal effectiveness. However, not all laws are set aside. The civil aspects of the law of Moses remain binding in their spirit, as Jesus affirmed in Matthew 5 that not one jot or tittle would pass until all is fulfilled. Acts 15:19-21 demonstrates this, as the Jerusalem council required Gentiles to observe specific laws from Moses while expecting further instruction through synagogue attendance on the Sabbath. Examples from Leviticus and Exodus, such as honoring the elderly, fair business practices, and prohibitions against bestiality and kidnapping, still apply, showing that these laws are extensions of the Ten Commandments, guiding community life. The administration of law has changed under the New Covenant, as described in II Corinthians 3:5-9, moving from a carnal, letter-based approach to a spiritual one empowered by the Holy Spirit. While the church lacks civil authority to enforce punishments, the laws themselves are not abolished but magnified to their spiritual intent, applicable to all, as God declared in Exodus 12 that there is one law for both Israelite and stranger. Thus, discerning which laws remain binding requires diligent study and meditation on God's Word, comparing scriptures to understand His will.

The concept of the applicability of God's law is central to understanding our spiritual responsibilities. Jesus Christ Himself declared in Matthew 4:4 that man shall live by every word that proceeds from the mouth of God, emphasizing the enduring relevance of all Scripture, including the Old Testament, which was the entirety of God's Word at the time He spoke. This raises a critical question: how can one live by every word if portions of the Old Testament are considered obsolete or ignorable? Further, II Timothy 3:15-17 affirms that all Scripture is inspired by God and profitable for doctrine, reproof, correction, and instruction in righteousness, equipping the man of God for every good work. At the time Paul wrote this, the Old Testament was the primary Scripture, indicating that it contains all necessary instruction for salvation. This challenges the notion that certain laws are no longer applicable, as it suggests that every part of God's Word, including laws on the Sabbath, holy days, tithing, and food, remains relevant for our spiritual well-being. Jesus Christ reinforced this in Matthew 5:18, stating that not one jot or tittle would pass from the law until all is fulfilled, and since not all has been fulfilled, the law stands intact. Psalm 119:152 declares that God's testimonies are established forever, implying that His laws are an eternal constant. Ecclesiastes 3:14 adds that whatever God does is forever, with nothing to be added or taken away, reflecting the perfection and thorough consideration behind every law He has given. Acts 15:18 underscores that God knows all His works from the beginning, urging trust in His wisdom even when we do not fully understand His directives. However, not every law is binding under the New Covenant in a literal sense. The council in Acts 15 determined that physical circumcision, for instance, is not required to make and keep the New Covenant, highlighting a distinction between theological necessity and cultural or practical considerations. While circumcision was a sign of the Old Covenant, representing a deeper spiritual reality, as seen in Deuteronomy 10:16 and Jeremiah 4:4 where God calls for circumcision of the heart, it is not a mandatory physical act for New Covenant believers. Yet, dismissing any law as irrelevant risks losing the wisdom and benefit it offers, as human nature tends to ignore what it deems unnecessary. Paul's actions further illustrate this nuanced approach. In Acts 16:3, he circumcised Timothy as a concession to the Jews, not as a theological requirement, showing that while he did not consider circumcision a curse or inherently opposed to God's law, he understood its practical implications. Similarly, in Acts 21:24, Paul complied with purification rituals to dispel false accusations that he taught against the law, demonstrating his respect for God's ordinances even when not strictly required under the New Covenant. Ultimately, the danger lies in assuming that any law does not apply, as this attitude can place one in a special category, ignoring the broader intent and wisdom of God's instructions. While not every law is literally binding, we must approach all of God's Word with reverence, seeking to extract its spiritual lessons and apply them to glorify Him.
