KEY THOT: Jesus came to abolish the first (old) covenant by establishing the second (new) covenant. However, he abolished the first covenant by replacing its many sacrifices and offerings with the once-for-all offering of his own body as the atoning sacrifice for sins. He thus made the OT sacrificial system obsolete through his own body. In establishing the second covenant by his self-sacrifice at the Cross, He threw open the door of salvation to all nations, not just for Israel--though Israel has the first priority to enter. The first covenant law given by Moses was provisional and intended for Israel alone as a theocratic kingdom. The second covenant law of the Spirit of life is eternal and intended for whomever the Lord calls into that eternal kingdom with Christ as King. The new theocratic kingdom is not based on human government ruled by an earthly king, but an eternal government based on the Spirit of God through whom Jesus Christ rules as the heavenly King.
The new covenant ratified by Jesus Christ is a far more superior covenant in terms of time, space and scope: it is eternal, knows no geographical boundary and is for all nations. Everyone who becomes a member of this kingdom has been set free from the tyrannical rule of self, sin and Satan through the power of the indwelling Spirit. We have become citizens of this eternal Kingdom enjoying its blessings of righteousness, peace and joy in the Holy Spirit. We have also become children of God who is our Father in heaven. For this reason, we cannot keep this good news to ourselves: we must confess and proclaim it to those who are still under the grip of the kingdom of darkness.
We need to start praying for our pre-believing relatives, colleagues and neighbours who are still in darkness, to bring them into the kingdom. While there are many methods to share the gospel (tracts, books, videos, etc), we can only make disciples by the old-fashioned way: “baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you” (Mt 28:19-20). Making converts is easy work (“baptizing them in the name of the Father and of the Son and of the Holy Spirit”) but making disciples is hard work (“teaching them to observe all that I have commanded you”).
Father, give us grace to fulfill Your call to make disciples of all nations in the coming new year. You have given to us a mandate and mission to make disciples of all nations. Help us not neglect in our responsibility to make this Gospel known to everyone who has not yet known You. Amen.
