The Fall frustrates our ability as people to subdue the earth.
To subdue the earth (i.e. to rule it lovingly and carefully in God’s presence) is replaced by sinful man with a form of subduing that is exploitive. (Similar to how husband-headship as designed by God can be distorted into male-dominance).
Nevertheless in Christ the task of subduing the earth is restored.
In Genesis 2 subduing the earth involved multiplying humanity and filling the earth in order to expand the place of God’s presence (Eden) over the earth. In Christ this task is restored as we obey the commission to make disciples of all nations - again God’s presence and rule is being spread in the earth.
I think that it is this theological perspective that links the subdue-commission with the Abraham-all-nations-promise (also related to fruitful multiplying and filling the land) and the great-commission. (It’s all about mission!!)
I think subduing the physical earth in the sense of acting in caring ways toward God’s creation as people under God’s rule is very applicable to Christians as well. Just as Paul says that what we do with our bodies is important in part because these are the bodies that will be raised (1 Cor 6:13-14) so too how we treat this earth is important because this is the earth that will be ‘resurrected’ (Romans 8:19-21) even if one day all the elements are destroyed by fire before new creation but the same happens with our bodies.
And on that day Eden will be over the entire new heaven and earth that God creates so ultimately it is Jesus who is the man who sucessfully subdues creation!!!
Hebrews 2:7-8 You made him a little lower than the angels; you crowned him with glory and honor and put everything under his feet? In putting everything under him, God left nothing that is not subject to him. Yet at present we do not see everything subject to him.
But we will !!!!!
