Our present New Testament pursuing includes peace, love, sanctification, and building up (verses in prior post). All of these point toward New Jerusalem.
Additionally, 2 Timothy 2:22 entreats us to “flee youthful lusts, and pursue righteousness, faith, love, peace with those who call on the Lord out of a pure heart.” Our pursuing of righteousness is our pursuing of Christ because God has made Him righteousness to us (1 Cor. 1:30).
“We are expecting new heavens and a new earth, in which righteousness dwells” (2 Peter 3:13). Not only New Jerusalem, but also the entire new universe will be characterized by righteousness. Furthermore, Psalm 89:14 says, “Righteousness and justice are the foundation of Your throne.” Ultimately the throne is in New Jerusalem from which the living water flows for eternity (Rev. 22:1).
We also pursue faith. This faith is our conviction of things not seen, including New Jerusalem, the city with foundations toward which Abraham looked (Heb. 11:1, 10, 16). We pursue peace too, which comes from God our Father and the Lord Jesus Christ (start of Rom., 1&2 Cor., Gal., Eph., Phil) and is called “the peace of Christ” in Colossians 3:15. Additionally we pursue love, the love which is of God (Rom. 5:5) and is God Himself (1 John 4:16).
All our pursuing (and our fleeing also) is “with those who call on the Lord out of a pure heart.” To call on the Lord is to cry out to Him. This is an audible calling, as in Acts 7:59, and 9:14, 21. Here is much more on the Biblical history of calling on the name of the Lord. Given this long history, it is likely that even in New Jerusalem we will call on the name of the Lord Jesus.
Lord, bring me into the practice of 2 Timothy 2:22. Give me calling companions with whom I can call on You and pursue You as my righteousness, faith, love, and peace.
