Therefore as by the offence of one judgment came upon all men to condemnation; even so by the righteousness of one the free gift came upon all men unto justification of life (Romans 5:18).
Under the Old Testament, God’s blessings for the children of Israel were preconditioned on their obedience to the Law. They had to obey the Law to enjoy the benefits of the first covenant. For example, God had desired that the children of Israel walk as kings and priests before Him, but their obedience was a prerequisite for the blessings to take effect in their lives. In Exodus 19:5-6, He said, “Now therefore, if ye will obey my voice indeed, and keep my covenant, then ye shall be a peculiar treasure unto me above all people: for all the earth is mine: And ye shall be unto me a kingdom of priests, and an holy nation….”
However, they broke His laws and couldn’t enjoy the blessings. This isn’t the case with us today in the New Testament. Colossians 1:12 says, “Giving thanks unto the Father, which hath made us meet to be partakers of the inheritance of the saints in light.” We’ve been made partakers of the inheritance of the saints in the Kingdom of light. We’re sharers and participants in the blessings and benefits of the Kingdom-life reserved for all God’s children. This happened when you were born again; you were born with an inheritance.
You don’t have to try to “obey” the Law for God to bless you; you were born blessed (Ephesians 1:3). Christ already fulfilled the Law; you’re the fruit of His obedience: “For as by one man’s disobedience many were made sinners, so by the obedience of one shall many be made righteous” (Romans 5:19). Through the obedience of Christ, God’s gift: His blessing of righteousness was bequeathed to you.
Nowhere in the New Testament are we told to “obey God” or to “obey the Law”; rather we’re called His obedient children: “As obedient children, not fashioning yourselves according to the former lusts in your ignorance” (1 Peter 1:14). We’re described as having “obeyed” God’s Word of truth from the heart (Romans 6:17). So our blessings, our inheritance in Christ, aren’t preconditioned on obedience; rather, they are our birthright!
