God subjecting creation-Jesus-women-Jews in hope?

Hi there,
I have been thinking about Romans 8:20-23, and have fed into it other verses, and would appreciate some feedback. Romans says God subjected creation in hope to mankind - that is, he gave us a gift which we had the option of abusing.

In Acts 3:26, we find that God sent Jesus to Israel to bless them. This delighted me - so often we see Jesus coming only to be betrayed and to die by their hand, yet as Jesus said of the vineyard owner, "what shall I do? I will send my own beloved son, him they will respect". Jesus was sent as a blessing, which Israel chose not to recieve.

My wife and I saw "The Missing" last night, and really enjoyed it. It did remind me however, that God placed women under men's authority, and of how often we have abused that gift. A pastor/friend who deals with abused women once told me ta times, he is ashamed to be a man.

Likewise, when God sent Israel into exile after their rejection of Jesus, they went to the very lands which would become Christendom. Of all the lands where they could have gone, they were placed at the mercy of their younger brother, and we abused them. We had other options, as 2 Chronicles 9-15 testifies, but we abused those who have been given into our power.

My question then is, is there a common thread here, of God placing potential blessings at our disposal, of "subjecting them in hope" to us?

God bless, Colin
