Summary of passage: We groan as we wait for our future glory. Hope for what we don’t have makes it all the more sweeter when it arrives.
9) We/our bodies groan as we await Jesus’s Second Coming and the freedom he shall bring from death and decay. Creation also groans (in the previous passage) for the same reasons.
10a) We hope for what we do not yet have (in this case our future glory and resurrection and end of suffering) patiently.
b) Personal Question. My answer: Probably the same things we all wait and hope for. On this side of heaven, an easier/better life away from suffering, pain, anxiety, fear, etc. On the other side of heaven, Jesus and glory.
Conclusions: This was merely an exposition on the previous verses as Paul says the same things in different ways with different analogies.
End Notes: The firstfruits of the Spirit is we have a taste of what is to come as we experience a bit of Jesus’s glory here on earth, but we long for its fulfillment. Same thing with adoption. We await its fulfillment (Romans 8:15). All with perseverance.
The presence of the Holy Spirit in believers is evidence of our present salvation and a pledge of our future inheritance. We are already God’s children and we await our inheritance in Christ.
The redemption of our bodies (resurrection) is the final stage of our adoption. We see the first stage in Ephesians 1:5 and the second is us living as God’s children (Romans 8:14 & Galatians 3:25-26).
