Rom.14:17 – for the kingdom of God is not eating and drinking, but righteousness and peace and joy in the Holy Spirit.
This verse sums up the Christian life. Paul is adamant, the kingdom of God is not about a system of rules and religious observances. The kingdom of God is spiritual and closely related to the Holy Spirit. The book of Romans has a theme connected to the righteousness of God that comes by faith. Being declared righteous by faith in the sacrificial death of Christ opens the kingdom of God up to us. Peace with God, peace in our own life, and peace with others is the fruit of the righteousness of God in our lives. Having been justified by faith we have peace with God. Joy is also the fruit of being right with God. It is in access to the kingdom of God that we are filled with the Holy Spirit and our joy begins to overflow. Here is how Matthew Henry describes this verse.
“Righteousness, peace, and joy, are very comprehensive words; and each of them includes much, both of the foundation and the superstructure of religion. Might I limit the sense of them, it should be thus:—As to God, our great concern is righteousness—to appear before him justified by the merit of Christ’s death, sanctified by the Spirit of his grace; for the righteous Lord loveth righteousness. As to our brethren, it is peace—to live in peace and love, and charity with them, following peace with all men: Christ came into the world to be the great peace-maker. As to ourselves, it is joy in the Holy Ghost—that spiritual joy which is wrought by the blessed Spirit in the hearts of believers, which respects God as their reconciled Father and heaven as their expected home. Next to our compliance with God, the life of religion consists in our complacency in him; to delight ourselves always in the Lord. Surely we serve a good Master, who makes peace and joy so essential to our religion. Then and then only we may expect peace and joy in the Holy Ghost when the foundation is laid in righteousness.”
Stepping into the kingdom of God by faith is what the book of Romans is all about. Today you and I have access into this kingdom life. We can step into the righteousness, peace, and joy of the Lord, being filled repeatedly with the Holy Spirit.
