Romans 8:23 expands on 8:19 by including believers who also groan and eagerly wait for adoption and bodily redemption — the same eager longing.

In 2 Peter 3:11-13, the creation's longing culminates in the dissolution and renewal of heavens and earth, anticipating the new creation.

In 1 John 3:2, the future appearing and transformation into Christ's likeness directly parallels the revealing of the sons of God.

In Revelation 21:1-5, the new heaven and earth and God dwelling with people fulfill the creation's eager waiting for redemption.

Isaiah 65:17 prophesies new heavens and earth — the very renewal creation eagerly awaits in Romans 8:19, a prophetic fulfillment connection.

Galatians 4:5 explains adoption as sons through redemption, providing the basis for the sonship that creation awaits to be revealed in Rom 8:19.

Acts 3:21 speaks of the restoration of all things — the same future event creation longs for in Romans 8:19, a parallel hope.

In 1 Cor 1:7, believers wait for Christ's revealing; here creation waits for the revealing of God's sons. Both share eager anticipation of a future revelation.

Colossians 1:27 reveals 'Christ in you, the hope of glory' — the mystery now unveiled, whereas Romans 8:19 looks forward to the future revealing of God's sons.
