Romans 14:17 NKJV
For the kingdom of God is not eating and drinking, but righteousness and peace and joy in the Holy Spirit.
Paul was exhorting the church at Rome to be considerate of the beliefs of other Christians in matters of food and holy days. He asked that they not judge someone who did not see things the way they saw it, but rather let that person stand before God who is the judge of all. He pointed out that the things they were arguing over were not vital to kingdom living. He said that the kingdom of God is about righteousness, peace and joy in the Holy Spirit. As members of the kingdom, let us major in the major things and not be sidetracked by minor things. Let us humbly follow our own conscience as best we can, while making sure we pursue the obvious things. One of those things is peace. The Kingdom we belong to is a kingdom of peace. Until we are walking perfectly in the peace that cannot be explained any other way except it comes from God, let us pursue it. It was important enough to Jesus for Him to specifically tell His disciples He was leaving it with them.
