So God created mankind in his own image,
in the image of God he created them;
male and female he created them.
Sufficient to have stood,
though free to fall.
(Paradise Lost, Book 3, Line 99)
The good news? Jesus. God allowed his son to be lifted up so that we might be lifted back up as well. We're no longer sufficient to stand on our own, but in him we can stand.
Consequently, just as one trespass resulted in condemnation for all people, so also one righteous act resulted in justification and life for all people.
In his we're sufficient to stand, though we fell so long ago. So stand! We're made in God's image - grab hold of that! Claim it! And thank God that through his son, through his suffering, through the cross we are made able to stand up and be saved. Christ is sufficient. And that's enough.
